We got these to take the hose across the driveway to drain the soft water unit to the ditch. The hose fit great and the speed bumps are not too high and the car goes over them easily and they don't move from the place where we laid them. It's all good.
I use them for stop indicators in the garage. After a couple of weeks they don't offgas so much and I can't smell it unless I need to reposition one. But when new? Whew-eee they really, really stink.
Smell is rather strong as was mentioned by a couple of other reviews but I use mine outside of my garage door. They are just a tiny bit too small for a standard size hose but still adds sufficient cushioning when the car drives over the hose to protect it from being damaged.
I use these to cover the 10/3 extension cords across the gravel driveway.Fantastic fit & Doesn't crush under the 5000 + tractor weight driving over it.
I searched for the perfect cover for our hose and I am so glad I found these! They work perfect and do not bend or move when you drive over them. Others looked so flimsy. Not these! Worth the money.
Work perfect to cover electrical conduit on top of concrete
We ran power to two free standing patio covers and these worked great to cover spans of 3/4 inch galvanized conduit on the ground. They are durable and I was able to cut them easily to size with my mitre saw. Dense and solid and I am pretty sure these will last a long time.
