Descender - ART

In stock

The SPIDERJACK 2.1 BASIC mechanical descender from ART.

Much like the POSITIONER lanyard cam, it also comes with a wooden, mobile dynamic friction cam that can be activated by hand.

This descender model is smoother than the LockJack, as the dynamic friction cam helps get rid of jolts during descents due to the LockJack ball. Handling the SpiderJack is quicker for side movements and descents. 

For side movements, lift the mobile dynamic friction cam with your thumb (be careful not to overextend your thumb but to place it at the base of the mobile cam), and then tilt the mechanical adjuster down while braking with the mobile cam. Then slowly release the pressure on the mobile cam with your thumb, and THERE YOU HAVE IT, you’re descending. The thumb pressure applied to the mobile cam controls the speed.
To take up slack, just push the cord into the device from the top or pull the rope under the device. The weight of the rope (if there is enough underneath) will suffice to lift the SpiderJack back up.

Proceed in the same way for vertical descents, only place the right hand on the mechanical adjuster and the left hand on the rope first (like a figure-8 descender) as reassurance. This friction device requires a certain level of skill since there is no anti-panic system—meaning if you grab the device in your hand without using your finger to brake, you free fall to the moment you let go of the device. If you let go of the device!

It’s a bit less expensive than the LockJack and a bit easier to use but requires a lot of attention when using.

Practical info:
