The 2.1 version has a longer lever which includes a metal half-pulley to make it a bit easier to operate the device when the tail is deflected. The ‘Dyneema’ version includes a Dyneema sling to allow the 2 karabiner set up. This greatly facilitates the frequent changing of anchor points.

The Spiderjack 2 serves as a multi-functional, 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 does not require changing the clutch using different diameter ropes.
  • 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.


  • 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!

Like the SpiderJack 2.1 Basic but with the Dyneema Kit mounted. The Dyneema sling is attached on the body of the device but the ring must be fixed on to the karabiner of the device. On the other end of the sling you can attach a karabiner for the spliced end of your rope. The Dyneema Kit allows to change the climbing system much more easily than before, when climbing with more than one rope and anchor point.

Before climbing, always verify that the ring of the Dyneema Kit is connected onto your karabiner!
