Swivl-Eze Seat Clamp Mounts

Swivl-Eze Seat Clamp Mounts: Engineered for Stability on the Water

When it comes to securely fastening a boat seat to a deck or gunwale, few names carry the weight that Swivl-Eze does. As a brand backed by Attwood Marine and trusted by professional boat builders across North America, Swivl-Eze has spent decades engineering seat mounting hardware that holds firm whether you're drifting on a calm lake or pushing through choppy offshore swells. Their seat clamp mounts represent one of the most focused expressions of that engineering philosophy — hardware designed to connect seats to pedestals and decks with confidence.

What Makes Swivl-Eze Seat Clamp Mounts Stand Out

The defining feature of Swivl-Eze's seat clamp mount lineup is the patented Lock'N-Pin system. This proprietary locking mechanism is engineered to prevent unintentional seat detachment, and Lock'N-Pin products exceed ABYC Standard H31.6.1 — the benchmark safety standard for marine seat hardware. That level of compliance matters for anglers and boaters who need their seating to stay put under dynamic, unpredictable loads.

Swivl-Eze also offers clamp-style seat mounts that adjust in length — such as the clamp-on swivel mount that spans from 7" to 18" — making them an especially practical choice for Jon boats and vessels where non-standard mounting positions are common. These mounts feature powder-coated aluminum construction for corrosion resistance, and are compatible with the most popular seat mounting hole patterns in the industry.

Materials Built for the Marine Environment

Every Swivl-Eze seat clamp mount is constructed from materials chosen specifically for saltwater and freshwater durability. Marine-grade aluminum and stainless steel are standard throughout the lineup, with hard-anodized finishes and bead-blasted surfaces that close up aluminum porosity and resist the corrosive effects of spray, humidity, and UV exposure. Stainless steel springs and hardware complete assemblies that are built to last season after season without degradation.

Swiveling and Fixed Configurations

Swivl-Eze seat clamp mounts are available in both fixed and swiveling configurations to suit different on-water needs. Fixed mounts deliver maximum stability — ideal for captain's chairs where a locked position is preferred. Swiveling mounts provide a smooth 360° range of motion, giving anglers the freedom to rotate and reposition without leaving their seat. Many models offer a 3-degree tilt to enhance ergonomic comfort during long hours on the water.

Designed for the 238 Series Ecosystem

Many Swivl-Eze seat clamp mounts are engineered as part of the legendary 238 Series — widely regarded as the most used seat hardware system by American fishing boat builders. The 238 Series uses a 2-3/8" post diameter standard that ensures seamless compatibility between seat mounts, pedestals, post extensions, and base plates within the Swivl-Eze ecosystem. This interoperability makes it easy to mix, match, and upgrade components without worrying about fit.

Whether you're replacing a worn mount on an existing setup or building out a new seating system from scratch, Swivl-Eze's seat clamp mounts deliver the combination of safety certification, durable materials, and proven design that boaters and boat builders have relied on for generations.
