The DuraMag® Service Body is designed for continuous hard work with full length, heavy duty, long sills. What separates this body from the competition is the understructure; the difference is stunning. The general body construction is fully welded—never riveted or screwed together. Our proprietary door extrusions, coupled with compression latches and automotive bulb seals, produce the most watertight compartments available. The black polymer door latches are rivet-less for additional protection. All vertical compartments incorporate nitrogen struts to optimize performance in cold environments. Options: Key Fob Locking, Bed Liner
