The Rock Exotica Kootenay Ultra is a compact knot passing pulley designed for rescue, hauling, and highline systems. Two sealed ball bearings provide smooth and efficient rope movement, while a single locking screw simplifies tie off. Two additional attachment holes help separate tag lines from hoist lines to reduce interference and load rotation. The pulley accepts 8 to 19 mm rope, has a 39 kN minimum breaking strength, and a 6 kN working load limit.
