  • Publication number: 20070151805
    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.

  • Publication number: 20060260260
    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.

  • Publication number: 20060054386
    Abstract: A connector for use with a cable includes a cable guide having a channel through which the cable extends and a housing having a cavity configured and arranged to receive the cable guide. A plurality of interconnecting members pivotally interconnect the cable guide and the housing. In a first position, the cable guide moves toward a back of the housing and the plurality of interconnecting members allow the cable to be released. In a second position, the cable guide moves toward a front of the housing and the plurality of interconnecting members engage the cable. The connector is anchored to an anchorage point so that a longitudinal axis of the housing extends generally parallel to the cable when the housing is anchored to the anchorage point thereby minimizing damage to the cable during use.

  • Publication number: 20050161285
    Abstract: A ratcheting anchorage device for use with a lifeline when performing tasks on a surface includes an anchorage member proximate the surface, a support member, a ratcheting device, an elongate member, and a connecting member. The support member is configured and arranged to be supported by the surface proximate the anchorage member. The ratcheting device is operatively connected to the support member. The elongate member has a first end and a second end. The first end is operatively connected to the ratcheting device, and the second end is operatively connected to the connecting member, which is configured and arranged to engage the anchorage member. The ratcheting device is configured and arranged to ratchet the elongate member so that the elongate member becomes taut when the connecting member engages the anchorage member thereby securing the support member to the anchorage member.
