I've see this type of conduit for cables before, but these are really heavy duty and work really well. Very happy with the purchase and the quick shipping, thanks!
used to protect power cable to our travel home across our driveway. if you ever had to replace a power supply for RV it is not cheap. Works great and because of the yellow safety paint, people tend not to run over it unless they have to
Amazing, durable, sturdy, and as not broke yet even though we had over 3000 cars run over it. If you have any festivals or events where you need to wire and keep them safe this is the product
