As per Art Spiderjack web site

The Spiderjack 2.1 serves as a multifunctional, self-blocking rope control device for the running double rope. Subject to adequate practice the Spiderjack 2 allows for unique functions and movements resulting in a very dynamic as well as strength saving climbing in trees and other environments. Features and Functions

• Use with ropes according to EN 1891, 11-13 mm. Unlike the Lockjack the Spiderjack 2.1 does not require changing the clutch using ropes.
• Ready for use with just one karabiner Fastening the Spiderjack to the harness and fixing the standing rope eye requires just one carabiner. This makes the whole system a specially compact one plus the hand-over-hand movement becomes really efficient.
• Extremely smooth rope passage even under load As soon as you pull the line above the device the Spider turns from blocking into running position. This allows for two-handed as well as single-handed ascent or adjusting of work positioning even when there is little rope weight below to speed up the rope run. Pure efficiency at work here!
• Ergonomic release combined with line control The ergonomically designed release lever of the Spider features a groove on its inner side giving a redirection of rope. This way the climber‘s hands will not be affected by rope friction at all.
• Thumb brake allows for precise control of movement Some practice with the unique thumb brake will facilitate a very precise control of rope passage – from extremely slow to extremely fast. Trained experts really enjoy the Spider induced high-speed precision landings. Of course the brake system works just as well in „normal“ use. The brake pad is made of Guajak wood (guaiacum), a very hard wood, friction resistant and extremely durable.

NOTE

• Using the Spiderjack requires wearing a harness with a low attachment point. The lower the Spiderjack is attached, the longer are the arm pull movements.
• The Spiderjack has no panic-function! Therefore it is necessary to follow user instructions especially in the learning phase!
