Releasable double progress capture pulley for haul systems

Releasable, the TWIN RELEASE progress capture pulley is designed to set up 4:1 haul systems for work in confined spaces or for technical rescue. Releasing the cam is possible with the ergonomic handle. The brake integrated into the moving side plate and the main faceted sheave with single-direction rotation, offer additional braking and better control when lowering heavy loads. The two sheaves provide excellent hauling efficiency. The swivel facilitates operations, allowing the pulley to be oriented under load and direct connection of carabiners, ropes, or slings.

Detailed description
Double progress capture pulley with handle to release cam:
- Ergonomic handle for easy release of the cam
- Brake integrated into main moving side plate allowing comfortable and precise control when lowering heavy loads
