Spiderjack Dyneema

The Spiderjack serves as a multifunctional, self-blocking rope control device in conjunction with double rope technique. The Spiderjack requires just one karabiner, which means the system remains very compact and efficient. As soon as the line above the device is pulled, the Spider turns from blocking into running position, which allows for easy ascent or adjusting of work positioning – even when there is little rope weight below to assist the rope in falling through. The ergonomic release lever redirects the rope saving the climber’s hands from friction. A thumb brake allows for very precise, incremental control of the device. Use of the Spiderjack requires a harness with a low attachment point – the lower the Spiderjack is attached, the longer the arm pull movements.
