Notch Rook Triple Attachment Swivel Pulley - ST

The Notch Rook ST Triple-Attachment Swivel Pulley is specifically engineered for tree climbing harness rope bridges and complex rigging systems. It innovatively integrates a 360° swivel with three independent attachment points, effectively eliminating rope twisting and significantly enhancing maneuverability during three-dimensional movement within the canopy.

All three top attachment points feature integrated rubber O-ring spacers, which securely hold carabiners in place to prevent dangerous cross-loading caused by equipment flipping. The 53mm large-diameter aluminum sheave offers excellent rope efficiency and a breaking strength of 28kN. Certified to European CE EN 12278 standards, it is a premier choice for professional climbers looking to upgrade their rope bridge hubs.
