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.
Red Anodized Aluminum sideplates,
2" Aluminum sheave, Bushing,
and Steel axle.
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.
