RiaYer Premium 316 SS Marine Rail Base - Heavy-Duty 90° Socket Fitting

Upgrade your marine railing system with the RiaYer 90-degree vertical stanchion base. Specifically engineered for 1.2" O.D. (Outer Diameter) tubing, this socket-style fitting provides a rock-solid foundation for deck railings, handrails, and canopy supports. Unlike standard hardware, our base is machined with a precise 1.2" Inner Diameter (I.D.) to ensure a snug, wobble-free fit every time.

Key Product Features

  • 🛡️ Genuine 316 Stainless Steel: Investment cast from high-grade 316 stainless steel for maximum corrosion resistance in harsh saltwater environments—far superior to standard 304 steel.
  • 📐 Precision Socket Design: The 1.2" I.D. allows your railing tube to slide directly into the base, creating a seamless and structurally superior connection.
  • 🔒 Dual Hex Set Screws: Features two integrated set screws that clamp firmly onto the tubing, preventing rotation and ensuring the post stays upright under pressure.
  • ✨ Mirror-Polished Finish: Hand-polished to a high-gloss mirror finish, matching the premium aesthetic of modern yachts and powerboats.

Technical Specifications

Fitting Angle 90 Degree (Vertical)
Inner Diameter (I.D.) 1.2" (30.5mm) - Fits 1.2" Tubing
Outer Diameter (O.D.) 1.43" (36.3mm)
Base Plate Diameter Approx. 2.75" (70mm)
Material Investment Cast 316 Stainless Steel

Pro Installation Tips

Sealant Tip: When mounting on a fiberglass deck, we recommend using a marine-grade sealant (like 3M 5200) under the base plate to prevent water intrusion into the core.

Step-by-Step Installation

  1. Marking: Position the base on your mounting surface and mark the three screw holes.
  2. Mounting: Drill pilot holes and secure the base firmly using appropriate marine fasteners.
  3. Tube Insertion: Slide your 1.2" O.D. rail tubing fully into the socket.
  4. Final Lock: Tighten the dual set screws with a hex key until the tube is immobilized.

What's in the Box (Per Set)?

  • 1x RiaYer 316 Stainless 90° Rail Fitting
  • 2x Pre-installed Hex Set Screws
  • 1x Matching Hex Key Tool

The RiaYer Commitment

At RiaYer, we specialize in precision rigging hardware. Our marine rail bases undergo rigorous quality control to ensure every socket meets our strict 1.2" tolerance. We don't just sell hardware; we provide the peace of mind that your boat's handrails will stay secure season after season.
