Singing Rock Jack Descender

The JACK Descender is a compact descender for work at heights designed mainly for rope access and rescue operations. Its advantages are durability, maximum simplicity and intuitive operation. With JACK, work is fun.

• Can be used for positioning, ascending and descending on the work line, as well as for lowering and belaying persons
• Automatically locks the rope, allowing the user to concentrate fully on the work
• Speed of movement on the rope is conveniently controlled by the lever
• During development, emphasis was placed on maximum simplicity, intuitive rope insertion and smooth operation
• With an unloaded rope, the locking mechanism can be deactivated by pressing the cam and thus the rope can be pulled out of the device without using the lever - this allows the device to be used, for example, for belaying a lead climber or for quick movement on a flat roof
• Easy retrieval of the rope allows the device to be used for short rope ascents
• It is not necessary to disconnect the device from the harness when inserting and removing the rope
  
• Using a screw, the device can be permanently locked to the rope to create a non-removable system
• Lever and lock can be disassembled and cleaned if necessary
• Patented design with magnetic holding of the cam facilitates rope insertion
