The Petzl Tibloc Ascender is an ultra-light and small multifunctional ascender. It is used for climbing ropes, aiding a second, rescue, or as a hauling or pulley system. Because it is small, it is often used as a back-up supporting standard ascenders.
The Tibloc provides good grip even on wet, muddy, or even icy ropes because of its chrome-plated cam that is equipped with inclined teeth and slots that are self-cleaning. It is also a good substitute for Prusik knots when used for rope climbing movements.
Tibloc works with locking carabiners having uniform oval or round stock with a cross-section of 10 to 12 mm otherwise damage to the rope is likely. Hot-forged carabiners featuring T-shaped stock should not be used. The ascender is suited for a single rope with a diameter of 8 to 11 mm.
Both body and cam are made of rust-resistant chrome steel assuring you of a long service life. It weighs 39 grams.
