attwood Swivl-Eze Lock'N-Pin 7in x 7in Aluminum Pedestal Base

In this review of the attwood Swivl-Eze Lock'N-Pin pedestal base, the bottom line is simple: it is a practical, well-built mounting solution for adding a swivel seat to a boat where corrosion resistance and a clean appearance matter. The reviewer found it best for boaters who need a straightforward, durable 7in x 7in base that accepts a 3/4in Lock'N-Pin post; the aluminum build and brushed finish give a premium look while the Acetal Bushing provides a secure fit. Installation is simple for anyone comfortable drilling six deck fastener holes, though mounting hardware is not included.

Key Features

• Brushed aluminum finish: Provides a neat, marine-grade appearance and helps resist corrosion in normal boating environments.
• Acetal bushing: Ensures a snug fit around the 3/4in pin and reduces play for a secure seating connection.
• Seven by seven footprint: The 7in x 7in plate gives stable support and spreads load across the deck for seated passengers.
• Six-bolt attachment pattern: Allows a robust, evenly distributed mount to the deck when fastened with appropriate hardware.
• Simple retrofit: Designed to add seating to pontoons, fishing and cruising boats without modifying existing seat posts.

Who It's For

The attwood base is aimed at boat owners and DIY installers who want to add or replace a swivel seat mount with a compact, durable aluminum base that accommodates a 3/4in Lock'N-Pin post. It suits pontoon and small to mid-size fishing or cruising boats where a 7in x 7in footprint fits the available deck area.

Those who should look elsewhere include buyers who want a complete mounting kit out of the box, since the product does not include mounting bolts or screws, and anyone who requires stainless-steel or fully painted finishes for heavier saltwater use without supplemental maintenance.

Pros & Cons

Pros

• Solid build quality from aluminum gives a good balance of strength and light weight for marine seating.
• Acetal bushing delivers a precise fit that reduces wobble on the 3/4in seat post.
• Brushed finish looks tidy and offers added resistance to surface corrosion in typical use.

Cons

• Mounting hardware is not included, so buyers must supply appropriate screws or bolts for their deck material.
• A few users reported early surface rust on surrounding hardware or related parts, so extra care with fasteners and maintenance may be needed.
