In regards to heavy-duty cable protection, the Yellow Jacket Cable Protector is perfect when there is going to be heavy vehicular traffic. With a load capacity of 21,150 lbs ‘per axle' , there is still plenty of protection for cables, hoses, and wires from getting damaged from constant truck/vehicular traffic!! Yellow Jacket Cord Covers have elongation properties of 400-600%, compared to the competition that offers less than 250%. This means that the polyurethane used to make the Yellow Jacket Cable Covers can carry a high/heavy load before permanently deforming and can ‘stretch' a lot more before breaking.
