White PVC cable trunking of 40 by 40 mm in a two-metre length with its cover removed

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

  • 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.

On the listing

A PVC cable trunking of 40 × 40 mm, two metres in total length, described as an electrical installation channel with a cover, in white; precise measurements of 40 × 40 mm supplied in one piece of two metres; high-quality PVC with a stable cover for durable use indoors and outdoors; pre-punched fixing holes on the underside allowing simple and secure wall mounting; cable management for the tidy and safe routing of electrical and data lines in living and working spaces; and a two-part system of channel and removable cover giving convenient access to the cables laid inside.

Forty by forty, and which forty is unstated

The section is square, and that is the first thing that separates this from everything else in this hub.

Six other listings here publish a rectangle — wider than tall, made to lie along a skirting board and disappear. This one is as deep as it is wide, which takes a bundle that stacks rather than one that spreads.

What the page does not say is whether those forties are measured inside the channel or across the outside of it. The first bullet calls them precise measurements without saying precise about what, and no wall thickness appears anywhere that would let the two be separated.

That gap runs through this whole shelf: not one of the seven listings settles it. Read the figure as the outside until a maker says otherwise, and size up.

The holes, already made

The third bullet is the practical one. The underside of the channel arrives perforated for screws.

On a two-metre length that saves an amount of work worth noticing — marking out a line of holes and drilling through plastic without splitting it is the tedious half of a screw-fixed run. Here the base comes ready and the wall is the only thing left to drill.

No adhesive is named anywhere on this page. This is a screwed installation, and the listing does not pretend otherwise, which is a cleaner position than a channel that offers tape and hopes.

The screws themselves are not in the box. That is reasonable, since the right fixing depends on whether the wall is masonry, plasterboard or timber, and no maker can choose that from a warehouse.

A cover that lifts off

The fifth bullet describes a two-part system: the channel, and a cover that comes away.

That is different from a hinged lid, which stays attached to the base along one edge. A removable cover gives fuller access to the channel — useful when a run is being filled — and it is a separate piece to keep hold of during the work.

The second bullet calls the cover stable, and pairs the PVC with use indoors and outdoors. Trunking used outside faces sunlight and cold that indoor runs do not, and the claim is the maker’s.

Two metres, once

One piece. Not a pack.

That is the shortest supply on this shelf: five listings here provide between two and twelve lengths in a box. For a run behind a desk, one two-metre length is exactly what is wanted and nothing is left over. For anything longer it means ordering several, and there are no couplers on this page to join them with.

Nothing for the corners

No bends. No T-pieces. No end caps. No couplers.

A straight run with two cut ends is what this listing supplies, and a run that turns a corner or meets another run needs pieces that have to come from somewhere else. Two listings on this shelf include a set of accessories; the other five, this one among them, do not.

Before ordering

Measure the depth of the bundle, not just its width, because a square channel is bought for depth. Choose the wall fixings yourself, since none are supplied. And plan a straight run, or budget for corner pieces from another source.

More cable trunking

  • Weinmann and Schanz white cable trunking of 40 by 60 mm in two-metre lengths

    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

    • 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.

  • D-Line white half-round self-adhesive trunking with corner pieces, T-piece and end caps

    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

  • Gewiss pure white cable trunking of 40 by 60 mm supplied as twelve two-metre bars

    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

    • 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

    Yeemie Pro 7-in-1 reader, USB 3.0, seven slots and five cards at once, 5 Gbps stated, LED per slot

    Seven slots and five of them usable together, each with its own green light, on a reader that publishes the gap between those two numbers without ever explaining it.

    Host interface standard
    USB 3.0 — stated in the title and in the first, third and fourth bullets. The third adds backward compatibility with USB 2.0 and 1.1
    Stated link rate
    Up to 5 Gbps — stated in the title and in the third bullet, which puts it at ten times USB 2.0 and gives that older class as 480 Mbps. No megabyte-per-second figure and no card-side rate appears, and no condition is attached to the 5 Gbps figure
    Connector type
    Not published on the listing — neither Type-A nor Type-C is named. The fifth bullet describes a reinforced USB 3.0 cable and a robust heat-resistant connector without giving its shape
    Internal or external form
    External, on an attached lead — described throughout as a reader connected to a computer by its own cable. No bay mounting and no internal header appears
    Slot count
    Seven — stated in the first bullet as one CF slot, two SD, two TF (microSD), one MS and one XD. Seven slots against five cards readable together is a gap the listing prints and never accounts for
    Formats accepted
    CF, SD, SDXC, SDHC, microSD, microSDXC, microSDHC, TF, M2, MS and XD — stated in the second bullet, which names the complete XD-Picture series including Olympus and Fujifilm cards of 1 GB and 2 GB
    Simultaneous slot access
    Five different cards at once — stated in the first bullet as reading and writing five cards at the same time, and again in the title. The third bullet adds that each slot carries its own independent green LED showing its working state
    Stated protocol support
    Not published on the listing — no UHS-I and no UHS-II mode is named, and no SD version number appears. The page lists formats and stops there
    Cable arrangement
    A reinforced USB 3.0 cable, attached — stated in the fifth bullet alongside a robust, heat-resistant connector. No length is published, which is the figure that decides whether a desktop reader reaches the machine under the desk

    Fortura All-in-one crimping tool with twenty plugs, twenty guides, twenty boots and a spare blade

    The one kit in this hub that ships a replacement blade, packed with twenty plugs split across two categories and twenty insertion guides — and the dearest tool on the shelf.

    Connector positions supported
    Not published on the listing — the second bullet names cable categories and connector families instead: Cat5, Cat6, Cat6a and Cat7, with RJ11 and RJ12 telephone plugs. No position count is printed
    Pass-through capability
    Not published on the listing — the third bullet describes an optimised crimping mechanism and firm, loss-free connections, and never mentions trimming conductors at the front of a plug
    Ratchet action
    Not published on the listing — the optimised crimping mechanism in the third bullet is named without any lock, ratchet or release being described
    Integrated stripper
    Yes — stated in the first bullet as cutting, stripping and crimping with a single tool
    Integrated cutter
    Yes — stated in the same phrase as the cutting function of the tool
    Replaceable blades
    Yes — a replacement blade is listed in the fourth bullet among the accessories supplied. It is the only spare blade in this hub, and the trimming edge is the part of a tool of this kind that dulls first
    Punch-down tool included
    Not published on the listing — no punch-down or insertion tool appears among the accessories, and modules and panels are never mentioned
    Kit contents
    Ten Cat6a plugs, ten Cat7 plugs, twenty insertion guides, twenty boots, a replacement blade and a storage bag — stated in the fourth bullet. The fifth describes a solid metal frame and a non-slip grip that can be worked single-handed

    The only tool on this shelf that describes its own mechanism in detail — a parallel crimp held by a releasable lock — and the only one that never names a single connector it terminates.

    Connector positions supported
    Not published on the listing — the four bullets describe cutting, stripping and crimping, and name no connector, no position count and no category of plug. It is the only tool on this shelf that leaves the question entirely unanswered
    Pass-through capability
    Not published on the listing — no trimming blade at the front of the die is described, and the term never appears
    Ratchet action
    Yes — stated in the third bullet as a forced lock that can be released, credited with keeping crimp quality consistently high. The fourth bullet adds a lever transmission for less tiring work
    Integrated stripper
    Yes — stated in the first bullet as fast cutting to length and stripping of Cat cable by means of high-grade knives
    Integrated cutter
    Yes — stated in the same bullet, as the cutting-to-length function of those knives
    Replaceable blades
    Not published on the listing — the knives are described as high-grade and nothing says whether they can be changed when they dull
    Punch-down tool included
    Not published on the listing — this is a single tool rather than a kit, and no punch-down function or accessory is described
