These basic oarlocks are built to withstand the rigors of recreational or commercial boating. Heavy-duty industrial-grade bronze-alloy ship screws are recycled to produce these powerful oarlocks. The 5/8" diameter, 3-1/2" long shaft is precision-turned and drilled for a split ring. The horn opening is 1-5/8" with a 2-3/8" inside diameter. Oarlocks include Split Ring keepers. Sold individually or in pairs, so don't forget to order a spare.
