Attwood Marine Pedestals - 1.77" Snap Lock

Attwood Marine Swivl-Eze 1.77" Snap Lock Pedestals

Attwood Marine has spent more than a century engineering marine hardware that boaters can depend on in demanding on-water conditions. Within their deep catalog of seating systems, the Swivl-Eze Snap Lock 1.77" pedestal line stands out as a purpose-built solution that bridges solid stability with the practical economy boaters expect from a seat post system. If you are shopping the broader 1.77" Snap Lock pedestal category, Attwood is one of the most recognized names you will encounter — and for good reason.

What Makes the 1.77" Snap Lock System Work

The 1.77-inch diameter is the defining specification of this pedestal family, and Attwood engineers designed the entire Swivl-Eze Snap Lock ecosystem around it. Every component in the series is engineered to snap and hold together, creating a tight, solid fit without the rattles or play that can develop in lower-quality systems over time. The locking mechanism features a larger locking clip with a metal insert that allows posts to lock securely into their bases, adding an extra layer of safety. Releasing the post is as simple as pressing the button — intentional detachment is easy, but unintentional detachment is effectively engineered out of the design.

Posts in the Snap Lock 1.77" line are constructed from sturdy bright-anodized aluminum, which provides both an attractive finish and meaningful corrosion resistance in the saltwater and freshwater environments where boats operate. Seat mounts are finished with an E-coat process for additional durability and are designed to permanently lock into the post in any swiveling position, so a passenger or angler can orient a seat exactly where they need it without it walking out of position underway.

Adjustable Height & ABYC Compliance

Attwood offers Snap Lock 1.77" pedestals in adjustable-height configurations — including common ranges such as 16"–20" and 24"–30" — making the system flexible enough to fit a wide range of fishing boats, pontoon boats, and cruisers. These products meet ABYC H31.6.1 marine safety standards, reflecting Attwood's long-standing commitment to engineering products that comply with the highest regulatory benchmarks in the industry. That compliance matters particularly to boaters who want verified safety assurance, not just marketing claims.

A Versatile Platform for Fishing, Pontoon & Cruising Boats

Whether you are replacing a worn-out factory pedestal base plate, adding a new seating position to a fishing deck, or upgrading a pontoon lounge layout, the Attwood Swivl-Eze 1.77" Snap Lock platform is designed to accommodate all of those use cases. The system is available in a wide choice of bases, post sizes, and materials, so boaters can mix and match components to tailor their seating arrangement without starting from scratch. Attwood's broad dealer and parts network also means replacement components are straightforward to source when individual parts eventually need attention.

For boaters who value a seating system that combines mechanical security, corrosion-resistant materials, and decades of proven marine engineering, Attwood Marine's Swivl-Eze Snap Lock pedestals in the 1.77" Snap Lock category represent a dependable investment in on-water comfort and safety.
