Petzl Ascension
The Petzl Ascension is a comfortable and easy to use handled rope clamp, for use during rope ascents. The Petzl Ascension is particularly intuitive to use thanks to the overmolded grip and ergonomic upper part of the handle, to sit comfortably in the hand and to create a powerful pulling motion when used with one or two hands. The Ascension is designed with a generous lower hole to enable the easy attachment of two carabiners for a lanyard and footloop, and the toothed cam has a self cleaning slot to enable for seamless rope use whatever the weather condition. We have them in both left and right handed variations - for whatever your preference.
