D-Line Half Round Cord Hider 8×39in Paintable Raceway

The D-Line Half Round Cord Hider is an easy peel-and-stick, paintable cable raceway designed to conceal TV wall-mount wires and tidy visible cords with a decorative half‑round profile.

If you want a simple, low-skill way to hide cables running down a wall or along baseboards, this 8-pack of 39‑inch D-Line raceways gives long continuous lengths so fewer connectors are needed. Each one-piece channel snaps closed with a patented click-lock hinge and comes with a pre-applied adhesive backing for fast installation. The subtle half‑round shape blends with décor, and the plastic can be keyed and painted to match trims, walls, or media furniture.

How do I install the D-Line cable cover quickly and cleanly?

Installation takes minutes without special tools: peel the adhesive backing, press the raceway onto a clean, dry surface, open the hinged lid, lay the cables inside and snap the lid shut. For extra security you can pre-drill and screw the raceway in place. The single-piece design removes the need to cut separate lids and bases, so fitting is straightforward even around imperfect measurements.

• Peel-and-stick pre-applied adhesive for fast mounting
• Hinged lid with patented click-lock snaps shut securely
• Can be screw-fixed for permanent installations
• Long 39" lengths reduce the number of joins and connectors

Will the D-Line hider fit behind my wall‑mounted TV and look neat?

The half‑round profile is deliberately slim and decorative, allowing it to sit discreetly under a TV or along baseboards so cables appear intentional instead of messy. The internal cavity accommodates typical power, HDMI and speaker cables, and accessories like bends, tees and end caps are colour matched for a seamless finish. Rear grip tabs on connectors secure joins and hide rough cuts so the visible result reads as part of the room’s trim.

• Slim half‑round profile blends with décor around TVs
• Accessories (bends, tees, end caps) hide imprecise cuts
• Internal shoulders on connectors ensure a flush look
• Compatible with common low-voltage AV and power cords

Can I change the color or match the D-Line raceway to walls or trim?

Yes — the plastic is paintable for a tailored finish. Lightly sand the surface to create a key, then apply two thin coats of your chosen paint for an integrated appearance. Colour‑matched accessories are available, which helps minimize the need to paint corners or connector pieces.

• Surface keys with fine sandpaper before painting
• Apply two thin coats for best coverage and adhesion
• Colour‑matched accessories reduce visible variation
• Suitable for trim, wall, or furniture color matching

If you need alternate profiles, D-Line offers several other sizes for thicker cable bundles or different aesthetic preferences.
