A simple, durable ascender. Available in two sizes. Extra duty ascenders have forged 2024-T6 aluminum cams while the others models have Tenzaloy cast cams.
Any mechanical ascender can severely damage or destroy the rope if overloaded or shock loaded.
It is very easy to overload these devices when used in mechanical advantage hauling systems. They should never be used to catch a load in a dynamic situation such as belay. Available in free running and spring-loaded models.
