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
- Marking: Position the base on your mounting surface and mark the three screw holes.
- Mounting: Drill pilot holes and secure the base firmly using appropriate marine fasteners.
- Tube Insertion: Slide your 1.2" O.D. rail tubing fully into the socket.
- Final Lock: Tighten the dual set screws with a hex key until the tube is immobilized.
What's in the Box (Per Set)?
