Specifically designed for 1-inch trailer drive shafts, the crank handle drill adapter comes with a 1/2-inch drive socket adapter for a secure, wobble-free connection. Precision-polished surface of the drill socket adapter eliminates burrs, providing a smooth, safe operation every time you adjust your trailer. Complete hardware kit (including gaskets,, locking nut, and pins) ensures the trailer drill adapter installs quickly and stays firmly in place during use. Heavy-duty metal construction ensures the drill adapter for trailer jacks resists rust, corrosion, cracking, and deformation, delivering long-lasting performance for repeated use., Weight: 0.7495716908 pounds, Manufacturer: Ameble_E77_8115366
