Basic building blocks of most rescue systems
No detail has been overlooked in these high-efficiency pulleys.
These compound or complex system workhorses feature
precision sealed ball bearings to minimize loss of mechanical
advantage. The large carabiner hole supports multiple carabiners, and the smooth, rounded edges on the high-strength aluminum side plates minimize rope fraying. The bottom is shaped for maximum efficiency with Prusik hitches but also works well with Gibbs-type ascenders. Large anodized aluminum sheaves provide efficiency, and low-profile axle fasteners reduce snags when the pulley is moving.
