Legrand Wiremold C310 Cordmate III 10 Foot 11 Piece Cord Cov

The Verdict

Let’s be honest: exposed cables running along your baseboard look terrible. The Legrand Wiremold C310 Cordmate III is the most popular fix for that problem, and at 4.5 stars from 225 ratings, it’s clearly working for most people. But does it work for your situation? Here’s the real breakdown.

What’s Actually in the Box

The “11 piece” description undersells what you get. The kit includes one 10-foot pre-cut channel (the base that sticks to the wall), one 10-foot snap-on cover, one 90-degree elbow, one T-connector, one straight connector, and an end cap. That’s enough to route a TV’s power and HDMI cables from the outlet up to the TV mount with a clean 90-degree turn at the top.

The channel measures 1.2 inches wide and 0.67 inches deep — enough for two standard power cords or one thick HDMI cable side by side. If you’re running a soundbar cable too, you’ll be squeezing. The kit also includes adhesive tape pre-applied to the channel, so you don’t need to buy anything extra for smooth walls.

Build Quality and Real-World Performance

The plastic is rigid PVC, not the flimsy stuff you find on cheap no-name cord covers. It cuts cleanly with a hacksaw or heavy scissors if you need custom lengths, though the 10-foot length covers most TV installations without cutting.

The adhesive is the star here. On smooth drywall or painted baseboards, it grabs immediately and holds. Multiple buyers report it’s still stuck tight years later. One reviewer noted, “I was skeptical about the adhesive, but it’s been 18 months and nothing has budged, even in a humid basement.”

The snap-on cover fits securely along straight runs. The weak point is the corners — routing a thick cable through the 90-degree elbow requires some patience, and the cover can pop loose if you force it. Several reviewers mention this exact issue with HDMI cables that have thicker connectors.

What Buyers Consistently Praise

The most common refrain in the 225 ratings is how invisible this becomes after painting. The white plastic takes latex paint beautifully, and once painted to match your baseboard, it genuinely disappears. One reviewer wrote, “I painted it the exact color of my trim and honestly forgot it was there until I moved.”

The included corner pieces earn consistent praise too. Most cord covers force you to buy separate accessories, but this kit ships with everything for a typical TV install.

Where It Falls Short

Textured walls are the dealbreaker. The adhesive needs a flat, smooth surface. On orange-peel texture or rough plaster, it won’t stick for long. You can screw the channel into the wall (there are pre-drilled holes every 16 inches), but screws aren’t included, and you’ll need to drill pilot holes.

The stark white color is also worth noting. It looks clinical and unfinished until you paint it. Budget for a small can of touch-up paint and 30 minutes of extra work.

And if you’re routing more than two cables, this won’t be enough. The 0.67-inch depth means you’re limited to a power cord plus one slim HDMI. For a full entertainment center setup, look at the larger Cordmate II or run multiple channels.

Who Should Buy This

Buy it if: You’re hiding a TV power cord and one HDMI cable along smooth drywall or baseboards, and you’re willing to paint it for a seamless finish. It’s also ideal for renters who want a removable solution — the adhesive peels off without leaving residue if you go slow.

Skip it if: You have textured walls, need to route more than two cables, or want a plug-and-play solution that looks finished without painting.

FAQ

Will this stick to brick or concrete? No. The adhesive needs a smooth, clean surface. For brick or concrete, you’ll need the screw-mount method, and even then, drilling into masonry is a separate challenge.

Can I paint over it immediately? Wait 24 hours after installation to let the adhesive cure. Use latex paint — oil-based paints can degrade the plastic over time.

Does the included tape hold on baseboards? Yes, on painted or stained smooth baseboards. If your baseboards are raw wood, clean them thoroughly first, otherwise the tape won’t adhere well.

The Verdict

Rating: 4.6/5

The Legrand Wiremold C310 Cordmate III is the best cord cover kit at this price for standard TV installations. It’s well-built, the included fittings cover typical routing needs, and the paintability is what separates it from cheaper competitors. The adhesive limitation on textured walls and the need to paint are real tradeoffs, but for the majority of smooth-wall installations, this is the product to beat.

Buy it if you’ve got smooth walls and two cables to hide. Skip it if you’ve got textured surfaces or a full entertainment system’s worth of wiring.
