Descenders & Belay Devices

Advances in manufacturing have allowed for significant improvements in rope control devices, even simple belay devices for mountaineering are now hot forged and CNC machined allowing for tighter tolerances, ease of use and improved control. Auto locking devices and force limiting devices have also greatly influenced the techniques and systems used in modern rope access and rescue whilst significantly improving safety.

A safety gate on the moving side plate allows the rope to be installed easily while the device remains connected to the anchor.
An anti-error catch reduces the risk of an accident due to incorrect installation of the device on the rope.
The anti-panic function automatically stops the descent if the user pulls too hard on the handle.
Once locked, the rope can be taken up without having to manipulate the handle, allowing the user to make a reversible haul system.
The moving side-plate can be locked shut with a screw, allowing the I’D EVAC to be integrated into evacuation kits.
Open auxiliary brake allows the user to increase the friction in accordance with the weight of the load and the rope diameter, and to install or release a rope at any time.
