These Sky Hooks can lift and position heavy, awkward loads with a simple one-hand operation.The dovetail style base is designed to quickly mount to the existing tool post on your lathe. With the addition of the optional bolt-down adapter, the Sky Hook can be easily mounted to any suitable flat surface including mill tables and benches.Sky Hooks have a simple and easy to use friction brake mechanism, the operator can easily lift the load by cranking the handwheel in the clockwise direction. If at any point the operator lets go of the handwheel, the brake will engage leaving the load to remain at that set height. Lowering the load requires the operator to ease back on the brake lever next to the handwheel while controlling the rate of descent with their hand on the handle or by lightly applying pressure of their palm on the outer surface of the handwheel.
