No detail has been overlooked in these high-efficiency pulleys. These compound or complex system workhorses feature precision sealed ball bearings to minimize loss of mechanical advantage. The large carabiner hole supports multiple carabiners, and the smooth, rounded edges on the high-strength aluminum side plates minimize rope fraying. The bottom is shaped for maximum efficiency with Prusik hitches but also works well with Gibbs-type ascenders. Large anodized aluminum sheaves provide efficiency, and low-profile axle fasteners reduce snags when the pulley is moving.
Working-At-Height / Industrial Rope Access / Technical Rope Rescue
Working at height requires reliable, quality equipment. The ProSeries Pulleys can be used with confidence in work-at-height maneuvers for industrial rope access or technical rope rescue when used in accordance with the regulatory safety standards they fall under. Always use life safety equipment and gear according to the regulatory safety standards for which it is classified and/or certified.
