Prussik Minding Pulleys
With the movement back to prussik-based safeties gaining momentum, the need for prussik minding pulleys that integrate directly into mechanical advantage systems is growing. To answer that need, we've developed eight prussik minding pulleys.

A larger 4" sheave with 5/8" rope capacity makes the RP138 the largest pulley of it's kind; smaller compact packages make the RP137 and RP137D ideal for use in confined spaces or caves.

CMI Highline Pulley Highline Pulley
Stainless steel sideplates put the CMI Highline pulley a cut above the rest, providing the highest strength to weight ratio of any carriage style pulley. Extra wide 3" sheave easily passes knots in 1/2" rope. Large rigging hole accepts up to 3 carabiners, two smaller holes are for tagline attachment. Two pins stowed directly on the sideplates allow it to be used as a high strength tie-off.
