Springfield Marine Second Generation non-removable pedestal system in 2-7/8” offers a heavy duty base and post for today’s larger and faster recreational boats. The base is permanent mold high magnesium aluminum alloy with anodized finish for maximum strength and corrosion protection. Then a 2-7/8” heavy duty extruded post is pressed and hydra-formed into the base mechanically forming them together. This proprietary process allows maximum strength for a sturdy pedestal.
