Petzl’s Ascension is a handled rope ascender available in right- or left-handed models. It’s designed for ascending and occasionally for hauling (back-up). The chrome-plated, steel cam with teeth and self-cleaning opening safely grasps the rope, indeed in sloppy or frosty conditions. This rope ascender has lower holes for connecting Petzl’s SPELEGYCA lanyard and installing Petzl’s FOOTAPE foot loop with a quick link.
Need a reliable, comfortable ascender for rope access or vertical rescue work? The Petzl ASCENSION handled rope ascender is designed for efficiency, comfort, and control, making it a favorite among rope access professionals, arborists, climbers, and rescue teams worldwide.
Available in left or right-hand versions, the ASCENSION features a wide, ergonomic handle that provides a firm, secure grip—even when wearing gloves or operating in wet or muddy conditions. The over-molded grip increases comfort and reduces fatigue during long climbs or repetitive rope ascents.
This ascender is optimized for performance. The toothed cam with self-cleaning slot ensures reliable operation even on dirty or icy ropes, while the lower and upper holes allow for easy carabiner attachment of a foot loop or haul system.
Have you ever struggled with rope grab devices that slip or jam in harsh environments? Do you need equipment that stands up to constant use on rope access or confined space sites? The ASCENSION is engineered with durability and smooth rope glide in mind, so you can focus on your climb—not your gear.
