"This Yellow Jacket cover is designed to maximize safety around industrial, commercial, and public settings. This cover protects cables that run across high traffic areas while minimizing potential tripping and electrical hazards. A hinged lid makes it easy to place and remove cables during setup and tear-down. The yellow lid protects up to four cables with outside diameters up to 1-1/4"". These four cables are housed in four separate channels that are located just below the lid. The surface contains raised diamond treads that provide solid footing and vehicle traction in icy or wet conditions. Each section features built-in Dog Bone connectors that link additional four-channel Yellow Jacket cable protectors to cover long cable runs."
