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 its kind; smaller compact packages make the RP137 and RP137D ideal for use in confined spaces or caves.
