Abstract
This invention relates to safety anchors for attachment of safety lines. The prior art anchors have weak resistance to lateral stresses and are susceptible to failure. The invention provides a safety anchor comprising a U-shaped anchor member having a pair of ends, a base for the anchor member, a tensile stud, and a supporting means. The ends of the U-shaped anchor member are securely attached to the base while the base has an aperture through it between the ends of the anchor member. The tensile stud passes through the aperture in the base to secure the base directly to a roof structure. The supporting means securely supports the base above the roof structure.
