For work in confined spaces and technical rescues, it's vital to be equipped with specific devices. PETZL's TWIN RELEASE blocking pulley combines several advantages for successful missions.
- A pinless cam, lockable in the open position and disengageable using the ergonomic handle
- Excellent control when lowering heavy loads, thanks to the brake integrated into the main mobile flange
- High efficiency for 4:1 reeving systems with large-diameter, ball-bearing sheaves mounted in parallel
- A faceted main sheave with a single direction of rotation (optimum hoisting performance and fewer areas of friction with the rope)
- Simple triple-action opening of movable flanges
- Red indicator lights when flanges are unlocked
- Rope can be installed without removing the anchoring device
- A hole in the handle for a remote control cord
- A swivel to guide the pulley under load, with an additional attachment point for easier manoeuvring (accommodating a maximum of three carabiners).
