The Single and Double Progress Capture Pulleys from ISC Wales are available in both locking and non-locking versions.
The locking versions feature one way locking bearings which make these Haulers a complete lifting & lowering rescue tool suitable for the most difficult environments and heaviest loads. A one way needle bearing allows the pulley wheel to turn freely in an anti-clockwise direction but will lock in a clockwise direction.
The non locking versions feature bushed standard free running wheels.
A sliding cam can be activated to prevent loss of rope control.
