Attwood makes three closely related Lock'N-Pin seat mounts for the 3/4-inch pin seating system. Although all three have a 3° tilt, the spring, mount height and material differ. This guide explains the choices so you can replace the correct fitting without assuming all Lock'N-Pin mounts are the same.

Attwood 1002 vs 1002-S vs 1002-SS

MPN Version Installed height Pin and spring
1002 Spring-equipped, black E-coat 2 in Steel pin with spring
1002-S Lower-profile, black E-coat 1 in Steel pin without spring
1002-SS Lower-profile, stainless steel 1 in Stainless pin without spring

1002 uses a black E-coated steel body and spring-equipped pin assembly. Its installed mount height is 2 inches. 1002-S keeps the black E-coated steel construction but removes the spring for a 1-inch installed height. 1002-SS is also 1 inch high and uses stainless steel, including the pin. All are listed by Attwood as Type B mounts.

Choose the seat mountMatch the exact part number, the spring arrangement and the seat's existing mounting pattern.
Check the pedestal postThe 3/4-inch designation describes the Lock'N-Pin connection, not the outside diameter of every pedestal tube.
Check the deck baseIdentify your existing base and its threaded or non-threaded post connection before completing the seat assembly.
Seating restriction: These 1002-series mounts carry Attwood's ABYC Type B designation. Do not use them at a helm or driver position. Matching the mount alone does not establish that the entire pedestal system is suitable for a particular seat.

What to check before replacing a boat seat mount

  1. Look underneath the existing mount for a spring and compare its overall installed height. The spring-equipped 1002 and non-spring 1002-S are different configurations.
  2. Identify the original finish and metal. The stainless-steel 1002-SS is distinct from the black E-coated 1002-S.
  3. Verify the seat mounting pattern, fastener condition and available room beneath the seat. Do not drill based solely on a similar-looking plate.
  4. Match the original Lock'N-Pin post and deck base. Attwood does not recommend interchanging its Lock'N-Pin seating components with those from other manufacturers.
  5. Check the specific listing for included components. A seat mount is not an entire pedestal kit.
