Stokbord® polymeric cable protection tiles are the market leading, heavy duty utility protection system for underground cable and pipes.

Manufactured from high impact, recycled polyethylene polymers, Stokbord® heavy duty cable protection covers or, underground warning boards, have been specifically designed to withstand damage from plant and tools.
