Attwood 1002 Lock’N-Pin 3/4″ Seat Mount

The Attwood 1002 provides a spring-loaded 3/4″ steel pin with a comfortable, soft sit. Its 3-degree tilt supports varied seating angles, making it a strong choice for small to medium boats where a compact mount is preferred. Best for: boaters prioritizing a stable, cushioned seat with easy pin-release. Limitation: installed height is relatively low at 2 inches, which may affect taller seating configurations.
CLLOMAGY Boat Seat Base Mount (7″x7″ Pedestal Base)

It allows a flush deck install and smooth post insertion for steady seating. Best for: boat owners who want a solid pedestal base that easily adapts to most marine seats. Caution: requires drilling and six screws for a secure flush fit, which is more involved than a simple clamp-on option.

Limitation: clamp-on design may require precise fit to certain bench configurations; ensure mounting hole compatibility before purchase.

The Shoreline Marine mount features a sturdy stainless design with zinc plating to extend life in harsh marine conditions. It uses a 3/4″ pin-type mounting compatible with standard 7″ x 7″ seat mounts. Best for: small to mid-size boats needing a durable, corrosion-resistant mount with 360-degree seating capability. Limitation: may require additional hardware for some deck layouts; verify hole spacing before installation.
Buying Guide: How To Choose The Right Boat Seat Mounting Hardware
- What type of boat do you own? Pontoon, bass, or jon boats may benefit from different pedestal sizes or clamp styles.
- Do you need a swivel? If you frequently adjust seating direction for lines, rod handling, or visibility, a swivel base is advantageous.
- What mounting surface do you have? Flat deck, bench seats, or rails affect whether you choose a base plate, clamp-on, or clamp-with-swivel option.
- What is your preferred height range? Some mounts offer extended height ranges; check compatibility with your seat base and leg length needs.
- Is corrosion resistance a priority? In saltwater or harsh environments, zinc plating or stainless components offer extended life.
