Qualcraft 2481 Ladder Hook, Weather-Resistant, Steel, Powder-Coated

The guardian fall protection ladder hook provides an ideal method of securing the top of a ladder to a rooftop. When used with a paired ladder hook, both hooks fit over the top two rungs of the ladder and hook over the roof edge. Then the wing nuts of both hooks are tightened, holding the ladder firmly in place. These hooks are designed to fit single or extension ladders and are made from powder-coated steel for excellent durability and strength.
