Singing Rock JACK Descender

The Singing Rock JACK is a compact professional descender designed primarily for rope access, work at height, and rescue operations. Its design emphasizes durability, straightforward rope installation, and smooth, intuitive operation. The device automatically locks the rope when required, while an ergonomic control lever allows the operator to regulate movement and descent speed.

JACK can be used for positioning, ascending and descending on a work line, as well as for lowering and belaying personnel. The rope can be installed or removed without disconnecting the device from the user's harness. Easy rope retrieval also allows the JACK to be used for short rope ascents.
