3. About This Item
- Reinforced 7mm Steel Frame for Demanding Loads: The winch body is formed from thick 7mm steel, offering excellent rigidity and long-term durability for repeated tensioning and heavy-duty cargo applications.
- Permanent Weld-On Installation for Maximum Stability: Designed for bottom-mount placement, this winch welds directly to the trailer frame, creating a fixed anchor point that won’t shift under vibration or high-load pressure.
- Optimized Drum Design for Smooth Strap Operation: The drum geometry helps 4" straps feed evenly without bunching, allowing operators to tighten and release tension more efficiently during loading cycles.
- Protective Black Coating for Outdoor Durability: A corrosion-resistant powder-coated finish shields the winch from moisture, road salt, and long-term exposure, extending its service life in harsh environments.
- High Load Capacity for Professional Hauling: Rated at 5,500 lbs WLL and 16,500 lbs break strength, this winch is built to secure oversized and heavy freight safely and reliably.
