The bottom line: this stainless steel top plate with a reinforcing steel lip tube and acetal bushing is best for anyone adding or replacing seating on a pontoon or fishing boat where a secure, corrosion-resistant base and straightforward installation matter most. It stands out for fit and build quality while remaining a no-frills, functional part rather than a full mounting kit.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStainless steel top plate:\u003c\/strong\u003e delivers solid corrosion resistance and keeps the visible surface looking clean under typical marine conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReinforcing steel lip tube:\u003c\/strong\u003e adds strength around the pedestal opening so the base resists deformation when used repeatedly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAcetal bushing:\u003c\/strong\u003e provides a snug, low-wear fit with a non-threaded pedestal pin for reliable seat retention.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClear coat finish:\u003c\/strong\u003e improves appearance and provides an extra barrier against surface corrosion in salt or freshwater environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSix-bolt attachment:\u003c\/strong\u003e spreads load across the deck for a secure mount and reduces stress on any single fastener location.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe Lock'n-Pin 3\/4in base is aimed at boat owners who already have a non-threaded pedestal or who want to add a removable seat post that locks in place.
