Friction reducing pulley integrated into a carabiner! Keylock gate that does not snag on ropes or gear. Screwgate locking mechanism. I-beam construction for increased strength. Ideal for use in hauling or rescue systems. The 7075 series pulley runs on a dry lube IGUS bearing, which is seated on a high tensile stainless sleeve and spindle. Will rotate with loads up to 11kN before any deformation occurs. In the unlikely event that the pulley does deform, the carabiner still acts as a full strength (24 kN) carabiner. Anodized for protection against the elements, especially coastal and mountain enviroments.
