Unique in its design, the R-ALF Pulley is not required to have an internal brake and as a result it is capable of several thousand cycles and many arrests. Built in the R-ALF is an over-speed brake that the pulley will lock on and hold when a fall occurs. The load rated Becket Eye on the R-ALF can be used in combination with Prusik Pulleys to create a 3:1 or 5:1 Mechanical Advantage System. Extra pulleys and carabiners not included.
