Abstract
A detachable roof anchor having a fixed, permanent portion and a removable, reusable portion. The permanent portion includes a roof anchor base plate, two carriage bolts and a truss clamp having serrated edges that engage the bottom side of the roof rafter. Releasably attachable to the permanent portion is a pivoting D-ring attachment member held in place by a clamp plate bolted to the roof anchor base plate. The attachment member, while providing safe and secure attachment of fall protection devices, also permits a wide range of motion without compromising the safety of the worker on the roof.
