Electriduct D-2 Rubber Duct Cord Cover - 5 Feet Black Floor Cable Protector

One section of my house has very old wiring--no grounded 3-prong outlets and not very accessible for re-wiring. My immediate problem was that I bought a new TV and didn't realize it would have a 3-prong plug.An intermittent problem we had was when my son was visiting, there was no 3-prong outlet in his room to plug in his computer. For this purpose we had been using a cheap cord concealer to run a cord to a grounded outlet in the hall, but it could not handle a second cord.This cord cover easily handles two heavy duty cords in the main channel. Each cord is round and about a quarter inch in diameter. They are heavy duty extension cords like you would use for a power tool. There is still room in the conduit for a smaller cord or speaker wires, not to mention two additional small side channels (you'd have to thread wires through the side channels).This cover lays much flatter than our old cheap one. It's not perfectly flat but that may be because one of the cords has to make a quick right angle turn as it exits the conduit and the tension may affect the cord cover. Or maybe I should have worked on it longer out of the box, to undo the curve from being coiled. Maybe it will get better with time, but it's good enough for me, it's just barely not flat on the floor at one end.I am happy to get a brown cover to blend in better than the old gray one, but this brown does not remotely match what they call Red Oak around here. It's just plain brown. My floors are 50's golden reddish brown hardwood and I was hoping for a reddish brown (based on another review, not on the product photo). Oh well.

This cord cover met all my criteria: heavy-duty, the 1/2" tall enclosure easily fit my 3/8" dia. cord, AND precisely the odd length, 30 in., that I was seeking. It came tightly coiled and quite stiff but a spell at room temperature then warmth from a gas fireplace (hairdryer would also work) served to flatten it. Should hold-up very well on the floor of my workshop. Well worth the price.

Unfurled the loose spiral configuration it was shipped in, put the 10-ft piece flat on a tile floor with four heavy'ish boxes on top, and by next day it was close to all flat. The thick rubber was relatively easy to cut with an x-acto knife. I'm using a 5-ft piece between the wall and my computer table in the center of the room. Floor is tile. I cut a 1" semi-circular notch at each end of the center channel so the cords could go up the wall and cover could fit closer to wall.I've got two 12-ga AC cables running through the center channel, one for APC UPS and other for heavy-duty Belkin powerstrip. It's a snug but good fit. The second cable was more work to get in, but I found that holding the cable at a right angle and pushing directly while feeding it in the "curve" of the bent cable made it slip in smoothly. (Trying to push second cable in with my thumbs when flat against the slot was much more difficult.)After a couple days on the floor it got fully flat. It doesn't need any adhesive; stays in place nicely. I'm using it in a one-man design/photography studio, and it does not get a lot of traffic (mostly just me, occasionally a couple others). The exposed portion is only about 3 feet. Maybe for a longer run where there is more traffic by people who might not be expecting a lump on the ground, it might be useful to tack it down in a few places with adhesive on the underside. But overall, it's heavy, flat and sticks well. 5 stars for functionality.My only complaint would be color choices. In my low-traffic situation, I don't need it to be too obvious. No one is going to trip on it. I've got light tan tile. I got a grey cover, but would have preferred tan cover. (BTW, the grey is nice. Good neutral color and nice medium tone. If there'd been a warmer tone of grey as one of the choices, it would have been perfect for my specific use here.)

My Roomba vacuum was getting tangled in one of the cords in my living room. This covered and concealed the cord well and the Roomba can get over it without getting tangled. Perfect

Good thing is it comes in many colors. Bad thing is it really doesn't lay flat on the floor even after weighting it with heavy books for days. Channel not big enough for the power cable a four thin cables so I thought it wasn't laying flat due to the cables coming out so moved to another area on tile floor with only one thin power cord and it still did not lay flat and it was only a 3 foot long piece. Ordered some special tape to tape it down. Ended up covering the original 5 cables with Eapele product on Amazon which lays flat easily, has a much wider channel without being higher. Only downside to Eapele is it only comes in industrial black with yellow warning stripes, but much more flexible. and doesn't need adhesive to hold it down.

The center hole was larger than I thought and for that, I am VERY grateful. I bought the cover thinking I could cut it in half to house the 3 wires I was trying to run in 2 separate strips.. I was extremely happy when I discovered all 3 would fit in the center groove, especially as cutting this in half would have required some act of God.. its VERY SOLID, and WIDE. I was looking for exactly this information when I bought it but it wasn't in any review so I hope this helps you.In the center groove I fit: 1 Outdoor rated electrical Extension cord, a normal thickness HDMI cable, and a thinner cable which leads to a 3.5mm plug which is a typical headphone audio-out wire. [leading to plug for wireless headphone receiver on the other side of the room in my case] In other words .. its VERY large and it ships FLAT in a long box. When it arrived I tried to remember if I had ordered a set of ski's, and I don't ski... When I opened it I was very surprised that it was actually the runner.This one may cost more but I am so lad I chose this one. I suggest you do the same!
