发明名称 ROOF LIFELINE, SAFETY SYSTEM AND ANCHOR ASSEMBLY THEREFOR
摘要 A lifeline safety system for a pitched roof employs a frame for mounting a lifeline system above the peak of the roof. Shoulders extend from the frame and engage opposing sides of the roof. An anchor comprising a generally J-shaped bolt secures the bracket assembly to the roof. The bolt has a hook which engages the underside of the rafter. A nut has a pair of arms for torquing the nut to the bolt. In one embodiment, two roof mounting pods are pivotally mounted to a shoe which receives a retractable lifeline housing.
