These Molded Rubber Hose and Cable Bridge protectors are idea for heavy-weight applications, where cars and trucks will be crossing over hoses, cables and wires. While they would normally be subjected to crushing and abrasion, rendering them useless in most cases, these bridges simply drop over, for secure and reliable defense. With dividers inside the channels for neat cable runs, the bridges themselves are relatively lightweight, meaning they are easy to install and remove. Our RHCB12A model also has the option of an aluminum insert, which means that each time you need to change or inspect a hose or wire, there is no need to fully remove the bridge. Optional connectors allow for sturdy connections between bridges, allowing your coverage and protection to be as broad as required.
