CAMP Dryad Pro Pulley

The sealed ball bearings provide a 92% efficiency rating, which significantly reduces friction when hauling heavy loads. This makes the pulley much smoother to operate under tension compared to standard bushing-based models.

The Dryad Pro is specifically optimized for 9mm ropes. While it may accommodate slightly larger diameters, using ropes outside the manufacturer's recommended range can compromise the prusik-minding function and overall safety.

A prusik-minding design features side plates shaped to prevent a prusik knot from jamming into the sheave. This allows the knot to slide freely and automatically lock if the load slips, which is essential for building safe mechanical advantage systems.

Yes, the combination of an aluminum alloy body and a stainless steel axle makes it durable enough for demanding rigging and rescue applications. However, like all climbing hardware, it should be inspected regularly for wear and tear.

The double sheave design allows you to easily create 4:1 or 5:1 mechanical advantage systems by threading the rope back and forth between the pulleys. This configuration is standard for rescue teams and arborists who need to lift heavy loads with minimal physical effort.
