90° Vertical Socket Fitting. 1.2" I.D. / 1.43" O.D. | Accepts 1.2" O.D. Tubing.

Overview

Secure your marine rigging with the RiaYer 316 Stainless Steel Rail Fitting. Designed as a heavy-duty 90° vertical socket base, this fitting features a precise 1.2-inch Inner Diameter (I.D.) and a robust 1.43-inch Outer Diameter (O.D.). Simply slide your standard 1.2" O.D. rail tubing inside the fitting, and lock it down with the included set screws. Perfect for installing vertical stanchions, upright posts, or flat deck railings, this slide-in design ensures a seamless, wobble-free connection.

Key Features

  • 📥 Slide-In Socket Design: The fitting acts as a robust socket. Your 1.2" O.D. rail tubing inserts directly into the fitting for maximum structural support.
  • 📏 Precision Dimensions: Machined with a strict 1.2-inch (30.5mm) inner diameter and a 1.43-inch (36.3mm) outer diameter, providing perfectly snug fit without loose gaps.
  • ⚓ 316 Marine-Grade Steel: Crafted from solid 316 stainless steel, offering superior resistance to saltwater pitting and corrosion compared to standard 304 or zinc alloy fittings.
  • 🔒 Dual-Screw Locking: Once the tube is inserted, dual hex set screws tighten against the tube wall, locking it firmly in place to prevent rotation or pull-out.
