Roof Topper™ supports raise conduit or raceway 4 in or more off the roof surface to meet the requirements of the 2014 NEC for temperature adjustment for circular conduit. Made of UV rated, 100% recycled material, the heavy duty base sits on the roof deck without the need to attach it to the roof surface with mechanical fasteners. Roof Topper™ supports stand up to extreme roof conditions, protecting and elevating your conduit or raceway above the roof deck. Roof Topper™ is available in a variety of sizes and configurations. They ship assembled with strut and threaded rod installed on the base. On our E series supports, the strut is attached with end clamps, reducing cost without any loss of strength. New to the line are three styles, 5-5/8 in h with a SLED on the base that slides on the roof surface, protecting it from damage caused by expansion and contraction.
