Abstract
A device, system and method are used for hoisting and lowering a load. The device has a front plate that may be displaced to reveal a sheave. The device also has a friction accessory. The friction accessory is arranged to create friction between a rope and the device when a load is suspended from the device using the rope and where the device is secured to a support structure. The system may be prepared by an operator, having ascended to an elevated location, and further allows the operator to lower the load from the elevated location prior to descending.
