The Stopfor® B trailing rope grab is specially designed to be incorporated in a fall arrest or travel restraint system where worker mobility and fall protection is required. This innovative fall arrester is developed around the roll-over cam braking principle where in the event of a fall, the unit rotates to exert pressure on the cam axle to effectively stop the fall. This is accompanied by the introduction of friction via a bend within the lifeline. This ingenuity in design introduces a fall deceleration distance that is exceptionally smooth, controlled, and low in force. The unit will function impeccably in a panic grab scenario.
The design of the Stopfor® B offers impeccable auto travel in both ascent and descent mode. Because the device functions without a locking jaw, little damage to the lifeline is caused when dynamically loaded. The Stopfor® B is offered in two models, WB58 and WB58P. Model WB58P includes a park feature that allows the rope grab to remain in a selected position on the lifeline. e. Tractel recommends to use a lanyard with a maximum length of 3 ft. (0.9 m).
