Attwood Swivl-Eze 278AO3AGS-1 AirGlide Boat Seat Slider Mount, 3-Degree Tilt, Fits 2-7/8 Inch Pedestal Post

The Attwood Swivl-Eze 278AO3AGS-1 is an AirGlide seat slider mount built for boaters who want to fine-tune their seating position at the helm or driver station. An integrated sliding mechanism, operated by a short handle, lets you glide the seat forward or backward to lock in the most comfortable position for the conditions. The mount incorporates a built-in 3-degree tilt into its base layout, angling the seating surface to optimize posture, reduce back fatigue, and improve visibility when running through rough water. It is designed to work alongside air-ride gas shock systems, adding shock-absorbing comfort on top of the slider and tilt functions for long days on the water.

Constructed from aluminum with a silver finish, the 278AO3AGS-1 is built to hold up in a marine environment and resist wobble over repeated use. It mounts onto a standard 2-7/8 inch diameter marine pedestal post. The mount is ABYC Code AO compliant, meeting the recognized safety standard for open-water seating hardware, so it is rated for use at the helm or driver position. This is the short-handle version of the 278 AirGlide Slider line; a long-handle version is offered under a separate part number for boaters who prefer that control style.
