The very compact and rope-friendly Microcender from Petzl is designed for use in self-belaying on a fixed rope. It does not have a quick attach and release system, but rather is installed on the rope using a removable pin. It completely encloses the rope, greatly reducing the chance of accidental disengagement. The device will slip on the rope if overloaded.
Works on single ropes, 9-13 mm diameter.w
Standards : CE - UIAA.
Read instruction manual and warnings carefully before using.
