This patented, modular cable protector bridge does more than just add extra cable channels to your Guard Dog Cable Protectors. It does so while providing both vehicular and foot traffic with a level crossing surface, complete with a textured surface to help reduce the risk of slips, trips and falls. That isn't its only claim to fame, either. It's the first expandable cable protection system to accommodate an unlimited number of channels. That means that no matter how extensive you need to make your cable or hose run, Guard Dog's got you covered. Intended for use with 5-Channel General Purpose Guard Dog Cable Protectors, these bridges are constructed of durable, all-weather polyurethane, and can protect cables and hoses with diameters of up to 1.5''.
