The PROTECH™ Single Pulley is a lightweight, high-strength Prusik-minding pulley designed for technical rescue, rope access, swift water rescue, ski patrol, tower work, and other applications where minimizing equipment weight is critical. Precision-machined side plates optimize the strength-to-weight ratio while maintaining exceptional durability in demanding environments.

Engineered with extremely low-profile stainless steel hardware, the PROTECH Single Pulley helps reduce snagging on rocks, roots, and other obstacles encountered in the field. Its unique axle assembly creates a smooth side plate design while providing impressive strength. The aluminum sheave rides on sealed ball bearings for outstanding efficiency and smooth operation, making it an excellent choice for small block-and-tackle systems and mechanical advantage setups.
