"Yellow Jacket cable ramps make it easy to protect cords and manage tripping hazards around public events, construction sites, entertainment studios, and more. This single-channel Yellow Jacket cable protector features a reinforced, hinged lid that makes it easy to position a 5"" diameter hose for the safest protection from vehicle and pedestrian traffic. An all-weather polyurethane construction gives this cable ramp the strength to protect expensive electrical cords from damage caused by vehicles weighing up to 18,870 lbs per axle. The ends of each cable ramp have built-in Dog Bone connectors that allow you to attach multiple units to cover any length of cable running through your warehouse or garage. All Checkers cable ramps and cable protectors are proudly manufactured in America."
