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 a permanent mold high magnesium aluminum alloy with an anodized finish for maximum strength and corrosion protection. A 2-7/8″ heavy-duty extruded post is pressed and hydra-formed into the base which mechanically forms them together. This proprietary process allows maximum strength for a sturdy pedestal.
