The Petzl Microcender is a cam-loaded rope clamp is perfect for progress capture usage, especially in ascending or in haul systems.
Petzl's Microcender is a smaller version with the exact same features as the Rescucender. The user connects directly to the grooved cam, which can slip if overloaded and thus act as a load limiter. The device will slide up the rope unaided, while a simple action will allow it to be moved down the rope. It is attached to the rope by two consecutive actions. This operation is slow but offers greater safety. Rope diameter: 9-13mm (3/8"-1/2") Weight: 162g / 5.7oz Standards: CE prEN 567, UIAA Note that this item of climbing safety equipment is non-returnable.

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.
