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! color: metallic (not as shown) wt: 2.3 oz.
