The PYRAMID is simple,
versatile and easy to use. Ribbed cooling
fins give good "no slip" grip for rope control
and the critical moments when rigging and
de-rigging your belay or rappel. Vary the
friction - for different ropes, partners
or steepness of the route by positioning
the small end (less friction) or large (more
friction) end against your locking biner.
Keeps ropes from kinking too!
