The Revolver Screwgate is an innovative carabiner with multiple applications. The carabiner has a screwgate and keylock nose so that it does not snag on ropes or gear. It features the same friction reducing pulley as the wiregate version, but this model will be fully certified as both a carabiner and pulley. This will make it ideal for use in hauling systems where exceptional safety is required. Technical details: The 7075 series pulley runs on a dry lube “IGUS” bearing, which is seated on a high tensile stainless sleeve and spindle. This will continue to rotate with loads up to 11Kn before any deformation occurs. In the unlikely event that the pulley does deform – and we have not seen one case yet – the biner still acts as a full strength (24Kn) carabiner. It has been anodized for protection against the elements especially coastal and rigorous mountain environments. Lubrication: The ‘IGUS’ bearing will run without lubrication, however like all gates and barrels a periodic cleaning and oiling will prolong the units life.
