150 ft. (45.7 m) automatic descent control kit with body sling, anchoring carabiner, rope spool and carrying bag.
The 3M™ DBI-SALA® Rollgliss™ Rope Over Wire Automatic Descent Device provides safe, automatic controlled descent from overhead cranes, towers, buildings or other heights. The system lowers the endangered person(s) at a controlled rate of 3 ft (1m) per second, vertically. In addition, the unit automatically adjusts to the user’s body weight. The 3M™ DBI-SALA® Rollgliss™ Rope Over Wire Automatic Descent Device comprises a braid covered steel cable with a safety belt fitted to each end. The cable passes through sheaves in the control unit, activating a geared brake system. The control unit may be bolted in place, or alternatively, attached by a carabiner to an eyebolt for semi permanent installation. This descent device is also extremely easy to operate. No power source or special skills are required. Once the unit is secured to an anchorage the rope can be dropped to the ground. The user can now slip on the support harness, step off the edge and be lowered to safety. As the first person is being lowered, a second harness is traveling up ready to be used by the next person.
