D-Line Half Round Cord Hider, 0.78 in x 15.7 in, White
A neat, paintable cover for one short, thin cable run; kits suit longer runs.
The short version
- Anyone hiding a single TV power cord between the screen and an outlet
- Renters who want a no drill option
- People who plan to paint the cover to match the wall
- You need to hide several cables or a thick power cord
- The run is longer than about 16 in and you do not want to join pieces
What owners like
- Hides a TV cord neatly without cutting into the wall
- Hinged lid makes it easy to add or remove a cable later
- Takes paint to blend in with the wall
Common complaints
- Small channel fills quickly; an HDMI cable plus a power cord can be a tight fit
- Unpainted white cover can still stand out on a colored wall
- Routing cables along the wall can mean buying longer cables
- A single 15.7 in piece is short, so longer runs need joined lengths or a kit

What it does
A short, single piece of D-Line's half round PVC cord cover with a hinged lid and peel and stick backing, sized for one or two thin cables such as a TV power cord.
- Hinged lid opens to lay cables in and snaps shut, so cables can be added or swapped later
- Half round profile designed to look like a decorative molding rather than a square channel
- Can be cut to length
- Paintable: D-Line says to key the surface with fine sandpaper and apply two coats
- Matching snap-on bends, tees and end caps are sold separately in the same 20 x 10 mm size
A tidy, paintable way to hide one or two thin cables over a short run, such as the gap between a wall mounted TV and an outlet. The trade-off is capacity and length: it only takes flexible cables up to about 8 mm across and covers under 16 inches of wall, so longer runs or thicker bundles call for a kit or the larger 1.18 in size.
