A 90° marine round rail base is designed for mounting vertical stanchions, handrails, or solar panel frames at a perfect right angle to the boat deck.
Key Buying & Installation Tips
Verify Tube Diameter: Always match the base precisely to your rail size. Marine standards are typically 7/8-inch (22mm) or 1-inch (25mm).
Drainage: Opt for investment-cast bases that feature built-in drainage holes to prevent standing water and crevice corrosion inside the socket.
Backing Plates: When installing a 90° vertical stanchion, always use a backing plate under the fiberglass deck to distribute the leverage load safely.

If you are replacing an existing base, tell me the outer diameter of your tubing or the distance between your current screw holes so I can find an exact drop-in match.
