KABLE KONTROLAtlas Cable Protector Wire Ramp - 3 Channel - 1 Pc - 35” Long Black & Yellow - 24000 Lbs Load Capacity - Rubber Speed Bump Wire Protector Cord Cover - CP9973

Best value, sturdy build an grips the floor so no sliding under foot

While it has a pungent rubber odor (had to leave it outside for a few days to off-gas), it's very sturdy, came quickly, and perfect for what I needed it for. I bought the 2-channel to use with my 10-gauge extension cord. It fits well across a sidewalk. As a bonus, if you put an LED strip in one of the channels, it will shine through the yellow flippy cover.

It was better quality then I expected.

Excellent product
