ISC One-Way Locking Double Progress Capture Pulley

The ISC One-Way Locking Single Progress Capture Pulley has a one-way locking bearing which is ideal for lifting and lowering. The wheel is locked in one direction, to create maximum friction when lowering/releasing.  In the opposite direction, the wheel runs freely, for minimum friction for lifting/hauling/tensioning. It incorporates a cam which automatically captures the load while lifting/pulling a load or tensioning a line. To lower/release the line the cam must be manually clamped by using the flexible Dyneema release cord and pinned clear of the rope during the lower/release of the line.
