Get the lock on quality. The 1.77 Inch group delivers a great combination of value and performance. Attwood Swivl-Eze Snap-Lock seat hardware combines the rock-solid stability of our larger diameter pedestal with the famous economy of our 3/4 Inch pin offering. Engineered to “snap-together” for a tight solid fit, this hardware is just as pretty as it is dependable – we bright polish every heavy-duty post for not just for great looks, but also for superior corrosion resistance.
