Abstract: The reusable roof anchor presents a novel approach for attaching a safety line to prevent the injury of workers while working on a roof. None of the devices in the prior art combine a reusable structure that can be adapted to any pitch of roof while providing maximum range of motion. The unique structure that joins a mounting platform with an attachment device by a pivoting joint enables this device to achieve this unique combination of benefits. Also unique to this design is the combination of the above attributes with an easy method of installation and removal. This design recognizes and addresses the four most important aspects that such a device must provide: safety, ease of installation and removal, adaptability, and range of motion. While other devices in the prior art address these concerns individually or partially, none address all four. Thus the reusable roof anchor for safety lines provides a major improvement in the safety of workers in the roofing industry.
