D-Line Half Round Cord Hider

D-Line Half Round Cord Hider is a one-piece, paintable adhesive cable raceway that neatly conceals TV wall mount wires and multiple cords with a snap-shut, patented hinged lid.

If you want the clean appearance of hidden cords without cutting into walls or hiring an installer, this pack of eight 39-inch D-Line raceways gives you long, continuous coverage that blends with your décor. Designed with a decorative half-round profile, pre-applied adhesive backing, and a patented click-lock lid, the system makes it simple to route and secure power, HDMI, speaker, and other low-voltage cables along walls and baseboards.

How does the D-Line design make hiding cables easier?

The D-Line half-round profile is a one-piece channel with a flexible hinged lid so there’s no separate lid and base to align or trim. The patented click-lock mechanism snaps closed for a secure hold and the lengths are long enough to reduce the number of connectors required for a tidy run.

• Pre-applied peel & stick backing for quick placement
• One-piece hinged lid avoids separate cutting of lid/base
• Patented snap-lock keeps lid closed without tools
• Eight 39" lengths reduce seams and connector use

Will this work around corners, baseboards, and TV mounts?

Yes — D-Line offers compatible bends, tees and end caps that integrate with the half-round lengths. Accessories have rear grip tabs and color-matched finishes so fittings remain secure and look continuous, even when cuts are imperfect.

• Accessory multipacks available for clean corner and tee transitions
• Rear grip tabs on bends and tees ensure snug connections
• Internal shoulders on connectors provide a flush appearance
• Longer lengths minimize the number of visible joints

Can I customize the raceway to match my wall color?

The raceway is paintable for a seamless look. To get the best result, lightly sand the surface to key the plastic, then apply two thin coats of your chosen paint. This lets the cable cover virtually disappear against painted walls or baseboards.

• Surface sands easily with fine-grit sandpaper
• Apply two coats of paint for even coverage
• Paintable finish suits matching to trim or walls
• Color-matched accessories maintain consistency post-paint

Who this is for: homeowners, renters, and AV installers who want a non-invasive, attractive solution for concealing cords and cables. It’s ideal for hiding TV and media wires, organizing power and data cables along baseboards, or creating neat, continuous runs without drywall work. Because the product is adhesive-backed and paintable, it’s also well suited to renters who need a reversible option and to DIYers seeking a fast, professional-looking outcome.
