Springfield’s Taper-Lock Round Base measures 9 inches with an 8-inch hole pattern, built from high-strength aluminum to withstand all outdoor marine conditions.
It’s a below-the-deck mount, requiring a 3-1/2-inch hole in the deck for installation, a straightforward retrofit for most boats.
It’s built to pair with any Taper-Lock post, sold separately, giving a complete seat mounting foundation when combined with the right post. Shop more seats, pedestals and slides.
