Ideal for mountain rescue, swift water, ski patrol, tower work or other technical uses, where equipment weight is a significant consideration, these lightweight, full-strength Prusik-minding pulleys feature extremely low-profile stainless steel hardware to reduce snagging on rocks, roots, and uneven surfaces. By machining the side plates, the thickness of the metal can be optimized to maximize the strength-to-weight ratio, a process that cannot be done with the traditional bent metal side plates. The unique axle assembly delivers a smooth side plate and impressive strength. The aluminum sheave is mounted on sealed ball bearings for high efficiency. Ideal for small block-and-tackle kits.
Note: Not compatible with 1/2-in (12.5-mm) or larger ropes.
Do not load a single side only of a double sheave pulley.
