The CMC PROTECH™ Double Pulley is a lightweight, full-strength Prusik-minding pulley designed for technical rescue, rope access, swiftwater rescue, ski patrol, tower work, and other applications where minimizing equipment weight is essential. Its compact design and efficient performance make it an excellent choice for small block-and-tackle systems and mechanical advantage setups.

Precision-machined side plates optimize the strength-to-weight ratio while maintaining exceptional durability. Extremely low-profile stainless steel hardware helps reduce snagging on rocks, roots, and uneven terrain, while the unique axle assembly provides a smooth side plate profile and impressive strength. The aluminum sheaves ride on sealed ball bearings for high efficiency and smooth rope movement, making this pulley a reliable choice for demanding rescue and technical rigging operations.
