Springfield Oarlock Socket 1840021 - Round Gunwale Mount, Fits up to 9/16 Inch Oarlocks, Sold in Pairs

The Springfield 1840021 is a round gunwale oarlock socket designed to give rowers a secure, quick-release mounting point for their oarlocks along the boat's gunwale. Each socket is fitted with a plastic insert that cushions the oarlock shaft, reduces metal-on-metal wear, and allows the oarlock to be dropped in and lifted out quickly for storage or when switching between rowing and other propulsion. The socket accepts oarlocks up to 9/16 inch, covering the sizing used on most recreational rowboats, dinghies, and small craft rigged for oars. Installation is straightforward: the socket mounts directly to the gunwale, giving a permanent, ready-to-use fitting so the oarlock itself can be removed when not rowing. This listing is for one pair of sockets (two pieces), enough to outfit both oar positions on a single boat. Built by Springfield Marine, a long-established maker of boat seating and rowing hardware, the 1840021 is a simple, durable replacement or upgrade part for anyone re-rigging a rowboat or replacing a worn or broken gunwale socket.
