Petzl TWIN RELEASE Double Pulley with Lowering Function
The Petzl TWIN RELEASE is a releasable double progress-capture pulley for setting up hauling systems with mechanical advantage (4:1). The integrated progress-capture can be released under load with the ergonomic handle, allowing for controlled lowering of the load without reconfiguring the system.
With two sheaves on sealed ball bearings (95% efficiency) and an auxiliary attachment point, the TWIN RELEASE is suitable for demanding rescue and hoisting applications, including in confined spaces.
