The SMC Kootenay Hx is the most advanced Knot Passing Pulley on the market. This is an entirely new and more compact design and lives up to its “HX” (High Strength) name as the lightest, strongest, most efficient, and durable pulley of its kind available. Sealed ball bearings provide optimal efficiency and help to reduce the performance-robbing resistance that is inherent in most multiple component systems. Adding to its versatility, the SMC Kootenay Hx Knot Passing Pulley may also serve as an edge roller for rope protection.
