The Rescue Pulley is a lightweight, full-strength, Prusik-minding pulley designed for technical rescue teams where minimizing equipment weight is critical. Ideal for mountain rescue, swiftwater rescue, rope access, and general technical operations, this pulley combines exceptional strength with compact dimensions for efficient field deployment.

Unlike traditional bent-plate pulleys, the Rescue Pulley features precision-machined aluminum side plates that allow material thickness to be optimized throughout the pulley, maximizing the strength-to-weight ratio. Sealed ball bearings provide smooth, high-efficiency performance, while durable aluminum side plates help protect the rope during operation. An extremely low-profile stainless steel axle assembly minimizes snagging on rocks, roots, and uneven terrain, making it particularly well-suited for challenging rescue environments.

Available in both single and double sheave configurations, the Rescue Pulley is designed for use with lifelines up to 13 mm (1/2 in) in diameter and is NFPA General Use rated.
