It features a high efficiency roller bearing sheave(s), threaded removable captive bar, and a full strength textile friendly becket. The uniquely profiled spine and removable captive bar aid in maintaining correct orientation. The design of the Revolver Rig is such that when using a connector attached to the becket, any friction between the connector and rope is minimized. MBS: 25kN
