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
- no additional friction is required up to a load of 200 kg
- compatible with a wide range of rope diameters 9.3 - 12 mm (see specifications for individual standards)
- parts in contact with the rope are made of stainless steel, which prolongs the lifetime of the device
- 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
- two color versions
