The Jumar ascender is one of the most popular rope clamps among climbers, hikers, cavers, and rescue teams. Available in versions for both right- and left-handed use.
Designed for ascending and positioning on a fixed rope, setting up pulley systems, and lifting loads. The ergonomically shaped handle, covered with rubber, provides comfort and thermal insulation. Ideal for gripping the rope during hauling or tensioning operations (up to 150 kg on the ascender).
The cam features a groove that self-cleans moisture, ice, and dirt. Compatible with ropes with a diameter of 8-13 mm.
