Specifications
- 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
On the listing
A D-Line 20 × 10 mm trunking multipack of 4 m with a half-round profile, self-adhesive, paintable, in white, containing 4× 20 mm (W) × 10 mm (H) × 1 m lengths and accessories; a decorative half-round profile said to blend discreetly into a room and to suit hiding cables for wall-mounted televisions, speakers and alarm cables, with the profile appearing as a natural top section above a skirting board; installation requiring no electrical or DIY knowledge, with a strong self-adhesive backing for peel-and-stick fitting and a one-piece design with a hinged lid for adding cables easily; a multipack containing 12 of the most popular accessories for hiding cables and joining lengths at common angles, with bends and T-pieces carrying rear retaining clips and a design that covers rough angled cuts or imprecise measurements; a paintable finish, keyed with fine abrasive paper and given two coats; and a pack contents list of 4× 1 m lengths, 2 flat bends, 2 external bends, 2 internal bends, 1 equal T-piece, 3 couplers and 2 end caps.
Twelve accessories, and all twelve are named
Two flat bends, two external bends, two internal bends, one equal T-piece, three couplers, two end caps.
Add them up and the total is twelve, which is the figure the third bullet gives. The two counts on the page agree with each other, and that is worth remarking on: a pack list and a headline count that disagree is a common enough fault.
The itemisation is what makes this pack plannable. A corner turned outwards needs a different piece from a corner turned inwards, and finding out which one is missing happens at the worst moment — halfway along a wall with the adhesive already down. Reading the list first means the run is designed before the box is opened.
The third bullet adds two details that only matter once you are doing the work: the bends and T-pieces have retaining clips at the back, and their shape is meant to cover an angled cut that came out rough. Both are admissions that the cut will be rough, which is honest.
Twenty by ten, and the shape underneath
The section is the smallest on this shelf and the profile is the only half-round one.
The fifth bullet labels the figures — 20 mm (W) by 10 mm (H) — which is more than most listings here do. What it still does not say is whether they are measured inside or outside, and on a half-round channel that is a sharper question than on a rectangular one, because the space inside a curve is not the rectangle the two numbers describe.
Not one of the seven trunking listings in this hub settles the inside-or-outside question. Here the geometry adds a second layer to it.
The point of the shape is in the first bullet: above a skirting board, a half-round profile reads as a moulding rather than as an addition. That is the argument, and at this section it works because the channel is small enough not to announce itself.
Adhesive, and only adhesive
The second bullet names a strong self-adhesive backing and no alternative appears anywhere.
That decides where this can be used. Clean, smooth, painted plaster holds it. Textured wallpaper, dusty masonry and anything cold and damp do not, and a run that lets go takes its cables with it.
It also decides who can use it: no drilling, nothing to make good afterwards, and the bullet says outright that no electrical or DIY knowledge is needed. On a rented wall that is the whole point.
Three listings on this shelf offer screws instead, and one of them argues explicitly against adhesive.
A hinged lid on a one-piece body
The same bullet names a one-piece design with a hinged lid.
That combination is the useful one for a run that gets added to. The lid stays attached — there is no separate cover to hold or lose — and it opens along the length so a cable can be dropped in and the channel closed again.
At twenty by ten there is not much room for growth, so the feature matters less here than it would on a larger section. It still means the run does not have to come off the wall.
The material that is never named
No PVC. No plastic of any kind. Nothing.
Five listings on this shelf name a material and two do not. Trunking is normally self-extinguishing PVC and this page does not say so, which leaves a buyer with the fourth bullet’s painting instructions as the only clue about what the surface is: key it with fine abrasive paper, then two coats.
That paintability is a real feature — it is how a white channel disappears into a coloured wall — and it is not a substitute for knowing what the channel is made of.
Before ordering
Measure the cables against twenty by ten before anything else, because this is a small channel and it may already be full on day one. Check the wall is smooth and clean, since adhesive is the only fixing offered. And read the accessory list against the corners in the actual run, which is the thing this listing uniquely lets you do.
