A retractable fall arrest block comprising a spring side housing member and a drum side housing member. A center support wall, defining a bearing housing, is secured between the housing members. A bearing assembly is mounted in the bearing housing to support a spindle. A spring side housing member is mounted to a spring side of the center support wall and a spring side cover is mounted to the spring side housing member opposite the center support wall to define a spring housing. A drum side housing member is mounted to a drum side of the center support wall, and a drum side cover is mounted to the drum side housing member to define a drum housing. The spindle extends into both housings. A spring is mounted in the spring housing. A drum is positionally fixed to the spindle in the drum housing. A clutch assembly is mounted to the spindle to stop the drum from unwinding.

Sealed retractable fall arrest block

A housing for the retractable is made from a lightweight, non-structural material, such as, plastic. The housing includes an internal reinforcement configured to bear the forces in a fall, thereby allowing the housing to be made from lightweight, non-structural materials.

Retractable lanyard lock mechanism

A rigid rail assembly for a fall protection system comprises a rigid rail segment and a hanger. The rail segment comprises an upper portion defining an elongate slot and a lower portion. The hanger includes a hanger body adapted to be connected to a support member and a hanger coupling member extending downwardly from said hanger body and which is adapted to be received in the rail segment slot. The rail segment lower portion has opposed elongate side walls extending downwardly and outwardly and a flange extending inwardly from each of said side walls. The flanges define a track for the wheels of a trolley.

A snap hook assembly includes a hook body defining a neck portion and a hook portion which form a capture area. A gate and a trigger are both pivotally mounted to the hook body. The gate is moveable between a closed position and an open position and is biased to the closed position. The snap hook is configured such that, when the gate is in the closed position, it cannot be moved to the opened position. The trigger is operable to release the gate, so that the gate can be moved from the closed position to the opened position.

Rebar snap hook

A clutch lock mechanism for a retractable lanyard includes a pivotal pawl with an engagement end and a sperrad or sperrad ring having teeth which face toward the engagement end of the pawl. One of the sperrad and the pawls are circumferentially fixed, and the other moves relative to the former. The pawl is pivotal movable between an engagement position in which the pawl engagement end within an annular ring defined on one side by the tips of the sperrad teeth and on the other side by the roots of the sperrad teeth and a non-engagement position in which the pawl engagement end is not within the engagement zone. The sperrad and the pawl are in contact with each other, such that, as one moves relative to the other, the engagement end of the pawl is positively moved into the engagement zone without the need to rely on centrifugal forces. Additionally, a housing for the retractable is made from, for example, plastic, and is provided with a reinforcement, such that the reinforcement bears the forces in a fall, thereby allowing the housing to be made from lightweight, non-structural materials.
