EDELRID Spoc Self-Jamming Pulley

This is an Edelrid Spoc. I purchased it last year and used it for about two days. I have put some weight on it a few times. There are scratches from use and transport. As this is a used item, please use it at your own risk.

A compact, ultra-lightweight pulley that is easy to carry. Designed for hauling loads and crevasse rescue.
Can also be used as an emergency ascender.
Features a highly efficient ball bearing for smooth operation.
The clamp cam for the backstop system has a shape that provides optimal grip even on icy or muddy ropes. The cam can also be locked in the open position for use as a simple pulley.
