Built from all-weather polyurethane, the Guard Dog's 3-channel drop-overs are made to protect both temporary and permanent fixtures such as pipes, conduits, and cable/hose lines. These protectors come in 18'' segments and are made with a patented 5-bar tread surface that provides safe, high-traction passage for both vehicles and pedestrian traffic in industrial, commercial and public environments. With two extra-wide channels, this system can accommodate various quantities and sizes of lines up to 1.325" outside diameter. Easy to store when not in use, the protectors are compatible with all standard Guard Dog 5-channel models, as well as other cable protectors with Dog Bone connectors. The drop-overs do not protect from abrasion from below, so should be used only on a flat surface.
