Versatile hand and chest ascender for efficient and fatigue-free climbing on ropes. The ergonomic design is suitable for both left and right-handed use. Thanks to the modular design, the fastening plate can be switched to the CHEST CRUISER plate, for example, with just one screw, allowing integration into different harness systems. A small eyelet at the top enables a cord to be threaded through so the ascender can be attached to the rope during various different uses. The large eyelet can hold up to three carabiners and is bent backwards so as to be constantly accessible and not to get in the way of the rope. Approved for up to 150 kg.
