JACK descender

Compact descender for work at heights designed mainly for rope access and rescue operations

JACK' advantages are durability, maximum simplicity and intuitive operation

Advantages:

* 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
