Replacing a boat-seat mount without the old package? Attwood 1002, 1002-S and 1002-SS are closely related Lock'N-Pin 3/4-inch system fittings, but they have different profiles and materials. Identify the original mounting arrangement first so the replacement matches the seat and pedestal.

Tell the three Attwood mounts apart

Manufacturer part Identifying features Installed height Construction
1002 Black E-coated steel, spring-equipped pin 2 in Steel
1002-S Black E-coated steel, non-spring pin 1 in Steel
1002-SS Stainless steel, non-spring stainless pin 1 in Stainless steel

The spring-equipped 1002 is 2 inches tall when mounted. The 1002-S and 1002-SS are both 1 inch tall, with the latter distinguished by stainless-steel construction. Each has the manufacturer's specified 3° tilt and Type B seating classification.

Measure the mount itself, not just the pedestal. A low-profile mount can affect the seating arrangement even if the post below it is the same nominal height. The shared Lock'N-Pin system designation does not make every seat assembly interchangeable.

Identification steps before replacing the mount

  1. Read the complete MPN. Look for 1002, 1002-S or 1002-SS. Keep the letters when matching an original part.
  2. Check the spring. The catalog's spring-equipped 1002 differs from the lower-profile no-spring versions.
  3. Inspect the material and finish. Black E-coated steel identifies the listed 1002/1002-S construction, whereas 1002-SS has stainless-steel construction.
  4. Confirm the seat fasteners. Compare the original seat-side hole pattern, hardware condition and mounting clearance with the exact part listing.
  5. Identify the mating post. These are mounts for the 3/4-inch Lock'N-Pin system, not the larger 2-3/8-inch 238 Series. Check the post and base together.
  6. Check the installation position. Type B fittings must not be used at the helm or driver position. Attwood does not recommend interchanging Lock'N-Pin components with other manufacturers' seating systems.

Replacing more than the mount? Identify the matching Lock'N-Pin pedestal post by height and connection and threaded or non-threaded deck base. For a different post system, see Attwood 238 Series seat hardware identification.
