Pulley TWIN RELEASE, Petzl

Releasable double progress capture pulley for haul systems.

The TWIN RELEASE progress capture pulley is designed to set up 4:1 haul systems for work in confined spaces or for technical rescue. 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.
