Springfield Jon Boat Seat Clamp with 360° Swivel
No drilling, no pedestal, no problem. The Springfield Jon Boat Seat Clamp mounts directly to the gunwale or bench of an aluminum fishing boat, giving you a stable, swiveling seat base without any permanent modifications. The clamp adjusts from 8" to 20-1/2" to fit a wide range of gunwale and bench widths, and the included 360° nylon bearing swivel lets you rotate freely to cast, fish, or board with ease.
Key Features
- Adjustable clamp range: 8" to 20-1/2" — fits a wide variety of jon boat gunwale and bench widths
- 360° nylon bearing swivel — smooth, full-rotation seat movement; 4-hole mounting pattern
- 6-7/8" swivel diameter — standard size compatible with most marine seat bases
- E-coat finish — corrosion-resistant coating for freshwater and light saltwater use
- Mounting bracket included — everything needed for installation in the box
- No drilling or permanent modification required
Best Use Case
Designed specifically for aluminum jon boats, flat-bottom fishing boats, and small utility boats where a clamp-on mount is preferred over a drilled pedestal base. Ideal for anglers who want a swiveling seat position at the bow, stern, or mid-ship bench without committing to a permanent installation — or for boats that are used for multiple purposes and need the seat removed between uses.
Parts Desk Insights
For a more compact or budget-friendly clamp option, see the Springfield Economy Jon Boat Seat Clamp (8" to 19"). If you’re looking to add a full pedestal system instead of a clamp mount, the Springfield Clipper Adjustable Pedestal Package is a popular choice for aluminum fishing boats. For a locking swivel upgrade, the Springfield Trac-Lock™ Locking Seat Mount pairs well with pedestal-based systems.
