Springfield 1600003
9-in round base · Deck pedestal base
Satin-finished aluminum pedestal mounting base. Requires an appropriate deck installation and a compatible Taper-Lock post.
Springfield Taper-Lock Boat Seat Bases & Posts by MPN
Springfield Taper-Lock boat-seat supports include separate deck bases, fixed-height posts and adjustable pedestal assemblies. These components share a Taper-Lock connection concept, but the correct replacement depends on the original part number, seat mount, height, locking requirements and deck reinforcement. This guide helps distinguish the specific products available through UsedRVParts.
Check the base, post and seat-mount interface
Deck baseSpringfield 1600003 is a 9-inch round satin-aluminum Taper-Lock base. Check its deck mounting area, plate design and post receptacle against the original installation.
Fixed-height posts1600406 is a short 6-inch Hi-Lo post. 1600607-L and 1600610 are 13-inch rise-post models, but their locking and included seat-mount details differ.
Adjustable pedestals1601002-L adjusts between 13½ and 20 inches; 1602016 is a taller 22½–29½-inch product. Neither is a height-for-height substitute for a fixed post.
System matching matters: A nominal 2⅜-inch post size alone does not establish compatibility with another manufacturer's base or a different Springfield pedestal series. Follow the original seat-system assembly and applicable boating seating requirements. Height, locking mechanism and deck strength all matter.
Springfield Taper-Lock base and pedestal MPN chart
Use the exact manufacturer part number to identify the deck base or post. Seat-mount packages and locking functions are separate characteristics and should not be assumed from the post's height alone.

Boat seat pedestal questions
Does a Taper-Lock base include the post?
Not for the separate 1600003 base shown in this guide. The post and other seat-mount parts must be selected for the specific assembly.
Are Springfield 1600607-L and 1600610 the same item?
No. Both are listed as 13-inch posts, but the locking mechanism and included seat-mount details differ. Use the exact original manufacturer MPN.
Will a taller adjustable pedestal fit the same boat seat?
Only after verifying the seat attachment, deck base, locking requirements and manufacturer-approved installation. A matching outside post diameter is not enough to establish suitability.
What is the height range of Springfield 1601002-L?
Its published adjustable range is 13½–20 inches. Compare this with the original installed seat height and available deck clearance.
Can Taper-Lock replace Springfield Mainstay or Attwood systems?
Do not assume interchangeability. Those seat-pedestal families have different mating interfaces and parts. Check the original manufacturer's complete seat-mount design.
