3M™ DBI-SALA® Rollgliss™ Rescumatic Automatic Descent Device works in both directions—and in any conditions—to deliver emergency victims to safety when danger is close. Easy-to-operate emergency device is equipped with a personal support harness and tough steel lifeline with safety belts at each end—so as one worker is being lowered to safety, a harness is on its way up to the next person. Strong, compact descender device has a geared braking system that senses bodyweight and moves at a steady 3 feet per second.

Bi-directional design When workers are in trouble, they can anchor this automatic descent device with the included carabiner or by bolting it, attach it to their personal harness, step into the sling, and step off the surface. Built for multiple rescues, its geared braking system saves time by lowering one person to safety while pulling a personal safety harness or body sling up to the next in line.  Steady descent Outfitted with an internal geared braking mechanism that senses body weight, this dependable safety product manages the descent at a steady 3 feet per second. At high heights and in dangerous situations, extra security is always a good idea. Escape device comes complete with a body sling and anchoring carabiner for live-saving support and a secure attachment. Built tough Available with 50 to 400 feet of braid-covered stainless-steel lifeline, this emergency rescue tool delivers trapped or isolated industrial pros to safety from any work level. Corrosion-resistant materials withstand the effects of moisture, flying debris, and repeated use, making this descent mechanism a life saver on any jobsite and any conditions—especially when technical rescue is out of the question.
