clamps the rope and blocks against a carabiner to create one-directional feed prevention.
The Pinch Cinch is useful for a variety of scenarios where you want to add backfeed prevention to a standard rope clipping carabiner, but don't have a cincher pre-installed on that carabiner. Or, you only want single-direction feed prevention. Having one or two on your LRS rack will prove handy on many pitches!
