This Sea-Dog fairlead is designed with a molded-in recess in the base. This traps the sealant in place to provide a more watertight fit. Stainless steel liner offers superior wear performance. Used for control lines, the stainless insert allows some directional control as well as the use of wire rope rigging in straight run applications. 1-7/16"H x 3/4"W. 1-1/16" in between mounting holes. 11/16" diameter eye.
