Shark A1 Adjustable Black Alloy Seat Plinth

The Shark A1 adjustable black alloy seat plinth raises a compatible marine seat while allowing the installed height to be tuned within a 120 to 170 mm range. The adjustable structure helps position the operator around the helm, windshield, controls, and legroom instead of committing to one fixed pedestal height.

Black alloy construction gives a strong lightweight support structure, while M8 316 stainless-steel fasteners add corrosion resistance at the mounting points. The plinth is designed as part of a modular marine seating installation where height and seat position can be matched more closely to the user and boat layout.

Confirm the required height range, seat and deck bolt patterns, load requirements, and clearance before installation. Secure the plinth to a structurally suitable mounting surface and make sure all adjustment hardware is fully tightened before use. Recheck fasteners periodically after exposure to vibration and repeated seat loads.
