Attwood Lock-N-Pin Base Plate, 7" x 7" (SP67739)
The Attwood SP67739 is a 7" x 7" square base plate for the Attwood Lock-N-Pin pedestal system. It mounts to the boat deck and accepts a compatible Lock-N-Pin post, locking together to prevent unintentional detachment of the pedestal during use. The 7" x 7" square footprint is the largest in the standard Lock-N-Pin base plate lineup, providing maximum stability for helm and fishing seat installations where deck space allows.

Parts Desk Insights
Best use case: The SP67739 7" x 7" base plate is the right choice when deck space is available and maximum stability is the priority — particularly on larger centre consoles, walkarounds, and offshore boats where the helm seat sees heavy use at speed. The square footprint distributes load evenly in all directions, making it more stable than a rectangular plate under lateral forces. If your mounting location is tight or obstructed, see the 4" x 8" or 6" x 8" rectangular options instead. Also available in threaded zinc-plated steel (67729T) and stainless bulk versions (67739) — confirm the correct variant for your post before ordering.
