The 1.5" Single Swivel Pulley combines a high-efficiency pulley and integrated swivel into a compact, lightweight device designed for rescue, rope access, arborist, and industrial rigging applications. By integrating both components into a single unit, the pulley reduces overall system length while improving rope alignment and operational efficiency.
Part of CMC’s ProSwivel Pulley series developed in partnership with Rock Exotica, this pulley features a pivoting side plate that allows ropes to be loaded and unloaded while the pulley remains attached to the anchor. The integrated swivel automatically aligns with the direction of pull to minimize twisting and improve system performance. A sealed ball-bearing sheave provides smooth, efficient operation, while the ergonomic design allows easy one-handed anchoring and rope installation.
Manufactured from CNC-machined aluminum and certified to NFPA General Use standards, the 1.5" Single Swivel Pulley offers an excellent balance of strength, durability, and compact size for demanding technical rope applications.
