Choosing Your Ascender

Petzl ascenders are designed for ascending fixed ropes, but they also have other uses including helping a second climber who is having trouble, hauling a victim out of a crevasse or up a wall, or self-belaying. For this, there are several types of ascenders: handled ascenders, chest ascenders, and backup ascenders.

Types of Ascenders

Hand Ascenders

With an excellent grip, these ascenders are primarily designed for ascending ropes. Their design also provides various ways to install the device on a rope in order to make a pulley system or haul a pack.

Locking Systems

Blocage avec gâchette à picots.

Rope Blocking with Toothed Cam (All Ascenders Except TIBLOC)

The teeth initiate the locking action and the cam pinches the rope. Blocking is optimal in a variety of conditions, including when the rope is wet, frozen, or muddy, all while reducing the effort needed to slide the device upward.

Rope Blocking via Carabiner Compression and Toothed Frame (TIBLOC)

The carabiner compresses the rope into the toothed frame. The self-cleaning slot enables use in a variety of conditions, including when the rope is wet, icy, or muddy. Ultra-lightweight solution using only the teeth and carabiner to block the rope.
