Petzl TWIN RELEASE double pulley with blocker

The twin pulley with the TWIN RELEASE blocker is designed for assembling 4:1 hoists for working in confined spaces or for technical rescue. The blocker cam can be operated using an ergonomic handle. The brake integrated into the movable sidewall and the faceted disc of the main pulley with unidirectional rotation provide additional braking and better control when lowering heavy loads. Two pulleys provide excellent pulling efficiency. The swivel hinge facilitates handling, allows the pulley to be oriented under load and the direct connection of carabiners, ropes or loops.
