We bought these cable protectors in July and use them in the shop to eliminate tripping hazards by keeping our 1" in diameter cables in check. The only negative is that they do have a very strong odor and need to be aired out. Once the smell dissipated they were fine. They work as advertised and so far we are pleased.
Very good quality. STINKS TO HIGH HEAVEN. I've left them outside, in 95 degree weather, for 3 weeks. Walk near them, you can still smell the rubber. I highly recommend these ... just be prepared to air them.
This worked great at our camp home as ran wire from generator through this to the tiny house. Able to now drive over it with no problems of hurting wire.
These covers are solid and heavy. Well worth the price, which was lower than an inferior product that did not last one year. They connect seamlessly and the hinge covers make it easy to lay in and take up my motorhome 50 amp power cord. The protectors do not slip when cars drive over them to park in the garage.
