The internal section decides how many cables actually fit inside

The best cable trunking for 2026

Trunking is the plastic channel that turns a handful of cables along a skirting board into one tidy line, and its whole specification is a cross-section. The internal width and height in millimetres decide how many cables fit, and the honest rule is to leave room rather than fill it: a channel packed to the lid cannot be added to and is hard to close again. Makers publish external dimensions on some listings and internal on others, and the two differ by the wall thickness, which is a real difference on the smaller sizes. The second decision is how it stays up. Self-adhesive trunking carries a tape on the back and depends entirely on the surface — clean, smooth and painted holds it, textured wallpaper does not — while screw-fixed trunking has a base drilled to the wall and a lid clipped over it, and it is the only kind worth using for a permanent run or a heavy bundle. Some profiles hinge open along their length instead of taking a separate lid. Then the accessories, which are what makes a run look finished rather than improvised: internal and external corners, flat bends, T-pieces and end caps, sold either inside the pack or separately, and the listing says which. Material is normally self-extinguishing PVC and the colour is white on most stock. Check the length per piece and how many pieces the pack holds, because a run is made of several. We compare internal width and height, external dimensions, fixing method, hinged or lidded profile, length per piece and pack quantity, accessories supplied, material and colour.

The ones worth keeping in the drawer

1. 

   kinkaivy 30 × 17 mm channel, 6 pieces of 400 mm, adhesive tape or screws, 13 connectors supplied

   The only kit on this shelf that puts both fixing methods in the same box — a clear mounting tape and twelve screws with anchors — alongside thirteen connectors for the corners.

   Internal width

   Not published on the listing — 30 mm is given as the width of the channel in the title and again in the first bullet as B30mm, and neither says whether it is measured inside the channel or across the outside of it. The two differ by the wall thickness, which is a real difference at this section

   Internal height

   Not published on the listing — 17 mm is given as the height, in the title and as H17mm in the first bullet, with the same ambiguity. No wall thickness is published that would let the two be separated

   External dimensions

   30 × 17 mm — the figures the listing publishes, carried here because the page never states which measurement they are. The first bullet writes them as B30mm and H17mm against a length of L400mm

   Fixing method

   Both — the second bullet names a clear PE mounting tape supplied free for fixing without damaging the wall, and screws and anchors as the alternative. The first bullet counts them: 12 screws and 12 anchors in the box. It is the only kit on this shelf that supplies both methods

   Hinged or lidded profile

   Not published on the listing — no lid, no hinge and no click closure is described. The channel is called a concealer throughout and how it opens is never stated

   Length per piece

   400 mm — stated in the first bullet as L400mm. It is the shortest piece length on this shelf, where the other six are supplied in one-metre and two-metre lengths

   Pack quantity

   Six pieces — stated in the title, which gives the total as 2.4 M for 6 pieces, and in the first bullet, which lists 6× the 400 mm length

   Accessories supplied

   13 connectors of various kinds, 12 screws, 12 anchors and one installation guide — stated in the first bullet. The connector types are counted but not itemised, which is the difference between this kit and the one other listing on this shelf that names each piece

   Material

   PVC — stated in the title

   Colour

   White — stated in the title. The fourth bullet adds that the channel can be painted to match the wall colour

   0609832535270

   • Supplies both fixing methods in one box, with the screws and anchors counted
   • Thirteen connectors included, so corners and joins do not need a second order
   • Never says whether 30 × 17 is the inside or the outside of the channel

   Best for: A first run along a skirting board or up to a wall-mounted television, where the corners are not known in advance and having thirteen connectors to hand matters more than a long straight length.

2. 

   twoja pszczółka 40 × 40 mm PVC channel, one 2 m length, pre-punched base, removable cover

   A square 40 by 40 channel supplied as one two-metre length, with the base already perforated for screws and a cover that lifts off rather than hinging.

   Internal width

   Not published on the listing — 40 mm is given as the width in the title and in the first bullet, which calls the figures precise measurements without saying whether they are taken inside the channel or across the outside

   Internal height

   Not published on the listing — 40 mm is given as the height, with the same ambiguity and no wall thickness published that would separate the two

   External dimensions

   40 × 40 mm — the figures the listing publishes, carried here because the page never states which measurement they are. It is the only square section on this shelf; every other listing here publishes a rectangle

   Fixing method

   Screws, through pre-punched holes — stated in the third bullet, which names the perforations in the underside as what makes wall mounting simple and secure. No adhesive backing is named anywhere

   Hinged or lidded profile

   Lidded — stated in the fifth bullet as a two-part system of channel and removable cover, offered as convenient access to the cables laid inside. The second bullet calls the cover stable

   Length per piece

   2 m — stated in the title as the total length and in the first bullet as one piece of two metres

   Pack quantity

   One piece — stated in the first bullet. It is the smallest pack on this shelf, where five listings supply between two and twelve lengths

   Accessories supplied

   Not published on the listing — no corners, bends, T-pieces, couplers or end caps are named, and no screws are supplied for the pre-punched holes. Two listings on this shelf include accessories and this is not one of them

   Material

   PVC — stated in the title and in the second bullet, which calls it high-quality PVC with a stable cover for durable use indoors and outdoors

   Colour

   White — stated in the title

   EAN

   5905753107356

   • The base arrives already perforated, so the run does not need marking out and drilling twice
   • A square section, which takes a deeper bundle than the flatter profiles on this shelf
   • No accessories at all, so corners and ends have to be sourced separately

   Best for: A short straight run — behind a desk, along one wall — where a deep square channel is wanted and there are no corners to turn.

3. 

   EDO 60 × 40 mm channel, 2 m, click-fastening hinged lid, screw or plug mounting

   The one listing on this shelf that argues against adhesive rather than offering it, with a lid that clicks shut so cables can be added to a finished run.

   Internal width

   Not published on the listing — 60 mm is given as the width in the title and never described as an internal or an external measurement. No wall thickness is published

   Internal height

   Not published on the listing — 40 mm is given as the height, with the same ambiguity

   External dimensions

   60 × 40 mm — the figures the listing publishes, carried here because the page never states which measurement they are. Two other listings on this shelf publish the same pair of numbers

   Fixing method

   Screws or wall plugs — stated in the third bullet, which is the only place on this shelf where a maker argues the point: it names screw fixing as offering maximum stability compared with self-adhesive solutions, and recommends it where a reliable fixing and a heavier cable load matter

   Hinged or lidded profile

   Hinged, with a click fastening — the title names a Klappdeckel, a hinged lid, and the fifth bullet describes a cover with a click closure that opens and shuts quickly so cables can be added or rearranged without dismantling the run

   Length per piece

   2 m — stated in the title

   Pack quantity

   Not published on the listing — the title gives a length of 2 m and no bullet says how many pieces make that up or whether more than one is supplied

   Accessories supplied

   Not published on the listing — no bends, T-pieces, couplers, end caps or screws are named anywhere on the page

   Material

   PVC — stated in the second bullet, which calls it high-quality PVC with a stable construction that resists deformation

   Colour

   White — stated in the title. The fourth bullet adds that the channel is also available in dark anthracite

   Amazon reference

   B0F6V9FL15 (same reference on 6 Amazon marketplaces)

   EAN

   5906843831601

   • A click-fastening hinged lid, so a finished run can be opened and added to
   • Argues for screw fixing over adhesive and says why, which no other listing here does
   • No pack quantity, so how much arrives for a stated two metres is unclear

   Best for: A permanent run carrying a bundle that will grow — a desk that keeps acquiring equipment — where the lid has to open again without the whole length coming off the wall.

4. 

   D-Line 20 × 10 mm half-round profile, 4 lengths of 1 m, self-adhesive, 12 accessories itemised

   The smallest section on this shelf in a half-round profile meant to read as part of the skirting, with an accessory list that names every one of its twelve pieces.

   Internal width

   Not published on the listing — 20 mm is given in the title and in the fifth bullet as 20 mm (B), the width, without saying whether it is measured inside the channel or across the outside. Labelling the figure as a width is more than most listings on this shelf do; it still does not say which width

   Internal height

   Not published on the listing — 10 mm is given as 10 mm (H), the height, with the same ambiguity. On a half-round profile the internal shape is not a rectangle, which makes the distinction more consequential rather than less

   External dimensions

   20 mm (W) × 10 mm (H) — the figures the listing publishes, labelled as width and height in the fifth bullet. It is the smallest section on this shelf by a clear margin

   Fixing method

   Self-adhesive — stated in the second bullet, which names a strong self-adhesive backing for peel-and-stick installation and says no electrical or DIY knowledge is required. No screw fixing is offered, and no screws are supplied

   Hinged or lidded profile

   A one-piece design with a hinged lid — stated in the second bullet, which names the arrangement as what makes adding cables easy. The lid stays attached to the channel rather than lifting off

   Length per piece

   1 m — stated in the title and itemised in the fifth bullet as 20 mm (W) × 10 mm (H) × 1 m lengths

   Pack quantity

   Four pieces — stated in the title as a 4 m multipack of 4× 1 m lengths, and again in the fifth bullet

   Accessories supplied

   Twelve pieces, each named: 2 flat bends, 2 external bends, 2 internal bends, 1 equal T-piece, 3 couplers and 2 end caps — itemised in the fifth bullet, and the third bullet gives the same total as 12 of the most popular accessories. The two counts agree with each other, and the third bullet adds that the bends and T-pieces carry rear retaining clips and that their design covers rough angled cuts and imprecise measurements

   Material

   Not published on the listing — no PVC and no material of any kind is named in the title or in any of the five bullets. What the fourth bullet does describe is finishing: the trunking and its accessories can be painted after keying the surface with fine abrasive paper and applying two coats

   Colour

   White — stated in the title, with the fourth bullet naming the paintable finish as the route to matching anything else

   Amazon reference

   B079WPWK5V (same reference on 6 Amazon marketplaces)

   EAN

   5060226648863

   • Every accessory named and counted, and the two counts on the page agree
   • A half-round profile that sits above a skirting board as if it were part of it
   • No material named anywhere on the page

   Best for: The drop from a wall-mounted television to a socket, or a speaker cable following a skirting board, where the channel has to be as close to invisible as trunking gets.

5. 

   WEINMANN & SCHANZ 40 × 60 mm wall and ceiling channel, 2 lengths of 2 m, perforated base, two-part body

   One of two listings on this shelf that says which of its two figures is the width and which is the height, supplied as a pair of two-metre lengths for wall or ceiling.

   Internal width

   Not published on the listing — 40 mm is named as the width in the fourth bullet, which writes the section as 40 × 60 mm (width × height). Labelling which figure is which resolves one ambiguity; whether the measurement is taken inside or outside the channel remains unstated

   Internal height

   Not published on the listing — 60 mm is named as the height in the same bullet, with the same limitation. No wall thickness is given that would separate inside from outside

   External dimensions

   40 × 60 mm, given in the fourth bullet as width by height, with a length of 2000 mm. The title writes the same figures as 40 × 60 × 2000. It is one of two listings on this shelf to label its dimensions rather than printing a bare pair of numbers

   Fixing method

   Screws, through a perforated base — stated in the third bullet, which names the base perforation as what makes the fixing stable and secure. No adhesive is named anywhere on the page

   Hinged or lidded profile

   A two-part body — stated in the third bullet as an upper and a lower section. Whether the upper part hinges or lifts away entirely is not described, and no click closure is named

   Length per piece

   2 m — stated in the title and in the fourth bullet, which gives the length as 2000 mm and the delivery as 2 × 2.0 metres

   Pack quantity

   Two pieces — stated in the title as 4 metres and in the fourth bullet as 2 × 2.0 metres. The total and the piece count agree with each other

   Accessories supplied

   Not published on the listing — no bends, T-pieces, couplers, end caps or screws are named. Two listings on this shelf include accessories and this is not one of them

   Material

   Not published on the listing — no PVC and no material of any kind is named in the title or in any of the five bullets

   Colour

   White — stated in the title and in the fourth bullet

   Amazon reference

   B0DM973JR8 (same reference on 6 Amazon marketplaces)

   EAN

   4262435954204

   • Says which figure is the width and which is the height, which five listings here do not
   • Names ceiling runs as well as wall runs, which no other listing on this shelf does
   • No material named anywhere on the page

   Best for: A run that crosses a ceiling as well as a wall — a cable brought from a consumer unit to a room across a garage or a cellar — where the channel is screwed up and left alone.

   KOMIB KOMpaniyeh International Business KK6040RW, 60 × 40 mm, 5 lengths of 2 m for 10 m, adhesive backing or screws

   The second longest supply on this shelf, at ten metres in five lengths, described in a single bullet that names neither the material nor how the channel opens.

   Internal width

   Not published on the listing — 60 mm appears twice in the title, once inside the part reference KK6040RW and once as 60 × 40 mm in brackets, and neither says whether it is measured inside or outside the channel

   Internal height

   Not published on the listing — 40 mm is given with the same ambiguity, and no wall thickness appears that would separate the two figures

   External dimensions

   60 × 40 × 2000 mm — stated in the title, which gives the section and the piece length together. The figures are carried at this line because the page never says which measurement they are

   Fixing method

   Both — the single bullet names simple mounting with a self-adhesive backing or with screws, described as flexible in use. No screws, anchors or tape quantities are listed, so what is actually in the box is not stated

   Hinged or lidded profile

   Not published on the listing — no lid, no hinge, no cover and no click closure is described anywhere. The bullet describes the material and the mounting and never the way the channel opens

   Length per piece

   2 m — stated in the title and in the bullet, both of which give five pieces of two metres

   Pack quantity

   Five pieces, ten metres in total — stated in the title twice and in the bullet, and the three statements agree with one another

   Accessories supplied

   Not published on the listing — no bends, T-pieces, couplers or end caps are named. The bullet mentions various sizes and models in the range without listing any accessory

   Material

   Not published on the listing — the bullet says high-quality material, robust and resistant to breakage, deformation and wear, and never names what that material is. The title carries the abbreviation VDE with no standard number beside it

   Colour

   Pure white — stated in the title as Weiß (reinweiß), and again in the bullet, which gives the plain white finish as what lets the channel sit unobtrusively in an interior

   EAN

   4262413586373

   • Ten metres in one box, which covers a whole room without a second order
   • Both fixing methods named, so the run is not committed to a wall type in advance
   • One bullet for the entire listing, and it names neither the material nor the lid

   Best for: Wiring a whole room or a workshop in one go, where the length in the box matters more than the detail in the description.

   Gewiss 40 × 60 mm channel, 12 bars of 2 m for 24 m, pure white

   Twenty-four metres in twelve bars, and a description four lines long that names no material, no fixing method and no lid — and gives the brand twice, differently.

   Internal width

   Not published on the listing — 40 mm is given in the title and repeated in the first bullet, with nothing said about whether it is measured inside the channel or across the outside

   Internal height

   Not published on the listing — 60 mm is given with the same ambiguity, and no wall thickness appears that would separate the two figures

   External dimensions

   40 × 60 mm — the figures the listing publishes, in the title and in the first bullet. Two other listings on this shelf publish the same pair, one of them in the opposite order, and none of the three says which measurement it is

   Fixing method

   Not published on the listing — no adhesive, no screws and no pre-punched base is named anywhere in the title or in the four bullets. It is the only listing on this shelf that does not say how the channel stays on the wall

   Hinged or lidded profile

   Not published on the listing — no lid, cover, hinge or closure is described. The second bullet gives the product type as a cable management cover, which names a function rather than a mechanism

   Length per piece

   2 m — stated in the title and in the first bullet, both of which describe the pack as bars of two metres

   Pack quantity

   Twelve bars, 24 metres in total — stated in the title and repeated in the first bullet. It is the longest supply on this shelf by a clear margin

   Accessories supplied

   Not published on the listing — no bends, T-pieces, couplers or end caps are named

   Material

   Not published on the listing — no PVC and no material of any kind appears. The second bullet gives the product type as a cable management cover and the fourth gives the colour, and neither says what the channel is made of

   Colour

   Pure white — stated in the title and in the fourth bullet, which gives the colour on its own line

   EAN

   4011598488060

   • Twenty-four metres in one pack, which is the longest supply on this shelf
   • The bar count, the bar length and the total agree in both places they appear
   • No fixing method anywhere, which is the one thing every other listing here publishes

   Best for: A large installation already specified elsewhere, where twenty-four metres of a known manufacturer’s channel is being reordered rather than chosen from a description.
