Designed by firefighters, our Roof Anchor quickly provides a secure anchor point for roof operations. Set the anchor on the roof and hammer the 1/2-inch (12.7-mm) diameter spike into the surface. When not in use, the spike folds into the handle for safe storage and transport. The Roof Anchor’s working strength will depend on the structural integrity of the surface, including any damage caused by the spike. Because of the highly variable strength of roof materials and difficulty in assessing this strength accurately. Depending on the operation, more than one anchor point may be required. It is the user’s responsibility to determine the structural integrity of the roof and to deploy the Roof Anchor appropriately.
