Jammy

The Jammy is a certified and ready-to-use auto blocking device! It is designed to fit all rope diameters, on one strand or two. The flexible aramid core with a polyamide sheath allows it to grip effectively even on small diameter ropes.

 

Lightweight, heat resistant and versatile, the Jammy is the ideal solution for creating auto-blocking knots (Prusik, Machard), to secure rappels and create hauling systems. EN certified for use as a sling, it can also be used to extend anchor points. The Jammy is an indispensable tool for all climbers seeking simplicity.
