Axle piece is removable so the device can be installed or removed at any point on the rope. The pin makes it difficult to remove device from rope involuntarily. Pin and axle are attached to the body of the ascender. For use with single ropes from 9 to 13 mm. CE / UIAA certified; 162 g.
Fit the extra-small Microcender ascender from Petzl into a shirt pocket and take it with you. Weighing only 5.5 ounces and able to accommodate a rope up to 1/2, its strength actually exceeds that of most other ascenders, despite its small size.
