Cable Winders for Boat Lifts & Dock Systems – USA-Machined

About

USA-Machined Cable Winders Collection Keep your lift lines straight and your boating days worry-free. Monster Bolts’ Cable Winders are precision-machined in the USA to wrap 7 × 19 aircraft cable evenly around drive pipes, eliminating cross-overs that weaken lines and chew up sheaves. CNC accuracy delivers groove depths that perfectly match cable diameter, while marine-grade aluminum resists salt spray without adding needless weight. Choose from winders that slide onto ½", ⅝", or ¾" drive pipes —covering everything from jet-ski cradles to 6-K-lb pontoon lifts. Pair them with our 316 stainless axle-bolt kits , aluminum sheaves , and drive-pipe attachment bolts for a complete, corrosion-proof upgrade. Whether you’re retrofitting an aging system or building new, Monster Bolts has the hardware to keep your lift spooling smoothly season after season.
