The Shelby winch is engineered to suit the demanding requirements of marine, recreational, industrial, and utility applications. You'll avoid the hassle of using other two-speed brands that require you to remove the handle to change speeds. Simply press the locking lever, and shift the handle from side to side to change gears or free spool. Higher load capacity means use in a wider range of trailers. Heat-treated gears provide long life, even under these high loads. Winch has a two-way ratchet that free spools in the "center" position. Zinc construction.
