## Features

- Designed to match industry-standard 5 1/4 inch mounting hole spacing, this seat base works seamlessly with most boat seats, swivels, and pedestal systems. For non-standard custom seats, pre-drilled holes allow for easy modification to fit unique mounting patterns.
- Forged from high-strength carbon steel with a corrosion-resistant black powder coat finish, this mount withstands harsh marine environments, UV exposure, and heavy regular use without chipping or premature wear. Solid all-welded construction supports up to 300 lbs of static weight for stable, reliable seating.
- Precision engineered ball bearing mechanism delivers seamless, jitter-free 360-degree rotation, allowing you to turn freely for fishing, sightseeing, or interacting with passengers without binding or sticking. Adjustable pedestal variants offer customizable height range for optimal seating position.
- Measuring just 6 1/4 x 6 1/4 inches overall, this low-profile mount fits easily in tight boat cabin spaces, with pre-drilled holes for quick, hassle-free installation using standard 1/4 inch mounting hardware. Compact form factor allows for easy removal and storage when not in use to extend product lifespan.
- Beyond boat seat mounting, this heavy-duty base works perfectly as a replacement swivel for bar stools, counter stools, workbench seats, and custom DIY furniture projects. Durable construction delivers reliable performance in both indoor and outdoor environments.
