Diamondback single tunnel modular cable and hose bridge systems for lines up to 6.5″ provide protection for valuable cable and hose lines while ensuring a method of safe passage for vehicles. They replace wooden and metal fabricated ramps. High density, all-weather urethane construction protects from damage by physical pressure and reduces cable and hose maintenance and replacement costs. The lightweight, modular design of interlocking 16 inch wide sections provides multi-length flexibility. Diamondback cable and hose bridge systems are intended for temporary installations only.
