<p><b>UL Classified to NFPA 1983 - General Use</b></p> <p>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, the use of a second Roof Anchor or multiple units should be standard protocol.</p> <p><b>Spike Length: </b>5-3/4 in. (146 mm)</p> <p><b><b>Closed Dimensions: </b></b>10.5 x 3.5in. (226x89mm)</p> <p><b> </b></p>
