Specifications

The K0405 MT Standard 10′ Arm is an extruded‑aluminum straight arm engineered for flip‑tarp systems used on dump trucks (typically 16′ beds). Designed by Mountain Tarp and sold through Wofford Truck Parts, this arm features a one‑piece, straight construction—no bends—and is compatible with either manual or electric motorized systems. The extruded aluminum material offers lightweight strength, corrosion resistance and simplified mounting (side‑mount spring assembly). With its 10′ length, the arm supports the full sweep of the tarp across the body, delivering consistent performance in demanding hauling operations. When you install the K0405, you benefit from a high‑quality, injection‑molded arm that fits tightly, installs cleanly and helps reduce downtime compared to older bent or welded arms.
