Abstract: A safety device with fall arrest and descending modes includes a housing, a drum, a lifeline, first and second brake assemblies, and a control. The drum is rotatably operatively connected to the housing. The lifeline has an intermediate portion interconnecting a first end and a second end. The first end is operatively connected to the drum. The first and second assemblies are operatively connected to the drum. The control is operatively connected to the first and second brake assemblies and has a first position and a second position. The first position selectively engages the first brake assembly in a descending mode and the second position selectively engages the second brake assembly in a fall arrest mode.

Abstract: A roof anchor comprises a pliable member including an interconnecting portion interconnecting a first portion and a second portion. The first portion and the second portion each include a securing portion with a plurality of apertures and a connecting portion with an aperture. A first notch and a second notch are proximate the junctures of each securing portion and connecting portion. The first notch and the second notch extend inward from opposing sides and toward proximate a middle of the respective first and second portions, and an aperture is between each first notch and second notch.

Abstract: A self-retracting lifeline includes a common, central brake hub having teeth on opposing sides and a lifeline assembly on each side of the brake hub. The lifeline assemblies include centrifugal clutch assemblies with pawls. The pawls are configured and arranged to engage the teeth of the brake hub to stop the lifeline assemblies when there is a sudden acceleration or a high rate of speed at which the lifeline assemblies turn to pay-out lifeline which causes the pawls to pivot and engage the teeth. The self-retracting lifeline may be operatively connected to a safety harness with a connector interconnecting the bottom of the self-retracting lifeline and the straps of the safety harness proximate a dorsal pad assembly and straps interconnecting the housing of the self-retracting lifeline and the straps of the safety harness above the dorsal pad assembly. The lifelines of the self-retracting lifeline exit the housing proximate the top.

Abstract: A roof anchor includes a base member and a connector. The base member has an intermediate portion interconnecting a first end and a second end. The first end and the second end are proximate one another at an end opposite the intermediate portion. A first interruption is proximate the junction of the first end and the intermediate portion, and a second interruption is proximate the junction of the second end and the intermediate portion. The first and second interruptions assist in bending the first and second ends outward from one another and from the intermediate portion. The connector is operatively connected to the intermediate portion proximate an opposing end relative to the first end and the second end thereby extending outward from the first end and the second end.
