Steelhead oarlocks are the light weight yet rugged oarlocks that are designed to make oars last longer because they are installed without drilling holes in the oars. Steelhead oarlocks clamp around the oars and can be easily adjusted to different positions to accommodate various width boats. Steelhead oarlocks are made of Marine grade AISI 316 stainless steel construction and feature a unique channel design that provides extra strength to withstand years of rugged use. 1/2" straight shank 2 per pack.
