Self braking device designed for descending rope and for belaying. Easily installed on the rope without disconnecting it from the harness. Anti-panic feature built in. When the user pulls too hard on the handle it causes the device to lock up. Easily releaseable after locking. Climbing is also possible with the addition of a rope grab and a foot stirrup or etrier. Can also be used effectively in haul systems. Great for rope access work. NFPA G.
