Roof Rollers may also be used to protect fire hoses, air supply and communication lines passing over sharp or otherwise abrasive edges. Lightweight aluminum frames are welded and then powder coated bright yellow for visibility, durability, resistance to corrosion and abrasion protection.
Features a pair of heat treated aluminum sheaves which measure 4'' long by 2-1/2'' in diameter. Each sheave is built with Oilite bushings on a 5/8'' diameter plated steel axle for efficiency and durability at a reasonable cost. The sheaves are paired in a unique frame design for secure placement over an assortment of edge structures. The flat base works equally well in either a horizontal or vertical configuration to meet the particular constraints of the rescue or work environment. A 1/8'' thick neoprene pad on the base helps to keep either model roller securely in place on smooth or uneven surfaces.
