I converted an old house to a large garage by tearing out the interior walls and floor - leaving only the concrete crawl space floor and the outer walls. This left a 16' span of two 3'' conduit pipes that housed the electric and water lines for the structure. Not sure how to safely address this and be able to drive a tractor or car across it, I tried out these cable protector/ramps. They are excellent! Very sturdy, easy to interconnect providing a seamless ramp that protects the utilities. Safe and much cheaper than having to disconnect all electric and run all new lines through the building! Highly recommended! -K.LaFever
