The PROTECH™ Double Pulley is a lightweight, full-strength Prusik-minding pulley designed for rescue, rope access, swift water, ski patrol, tower work, and other technical applications where reducing equipment weight is critical. Engineered with precision-machined side plates and low-profile stainless steel hardware, this pulley minimizes snagging while maintaining exceptional strength and durability in demanding environments.
Unlike traditional bent-side-plate pulleys, the PROTECH™ Double Pulley utilizes machined side plates that optimize material thickness for an outstanding strength-to-weight ratio. Its unique axle assembly creates a smooth profile while enhancing overall strength. Dual aluminum sheaves mounted on sealed ball bearings deliver high efficiency and smooth operation, making this pulley an excellent choice for compact mechanical advantage systems and block-and-tackle kits.
