Singing Rock Jack

Singing Rock JACK Compact Descender for Work at Heights

Designed primarily for rope access and rescue operations. Its advantages include robustness, maximum simplicity, and intuitive control. Working with the JACK is pure enjoyment. It can be used for positioning, ascending and descending on a working rope, as well as for lowering and belaying persons. It automatically locks the rope, allowing the user to fully focus on their work.

The rope movement speed is comfortably controlled by the lever.

During development, emphasis was placed on maximum simplicity, intuitive rope insertion, and smooth operation.

When the rope is not loaded, blocking can be disengaged by holding the cam, allowing the rope to be pulled out of the device without turning the lever – this makes it suitable for belaying a lead climber or for quick movement across flat surfaces such as roofs.

Simple rope taking-up makes it possible to use the device for short rope ascents.

When inserting or removing the rope, there is no need to disconnect the device from the harness.

Up to a load of 200 kg, no additional friction is required.

Compatible with a wide range of rope diameters (9.3 – 12 mm) – see specifications for individual standards.

The parts in contact with the rope are made of stainless steel, which increases the device’s lifespan.

With a screw, the device can be permanently locked onto the rope, creating a non-removable system.

The lever and safety catch can be disassembled and cleaned if necessary.

The patented design with magnetic locking of the cam simplifies rope installation.
