Sea-Dog 90-Degree Universal Hand Rail Tee, 1 Inch, 316 Stainless Steel - 290901-1

The Sea-Dog 290901-1 is a 90-degree Universal Tee fitting designed to create directional joints in 1 inch boat hand rail systems. As a Universal Tee, it is used where a rail run needs to branch or turn at a 90-degree angle, giving installers a clean, corrosion-resistant connection point without welding.

This fitting is constructed of investment cast 316 stainless steel, a grade chosen for its resistance to corrosion in salt water and marine environments, making it suitable for long-term exposure on deck hardware and hand rail assemblies. Installation requires a 1/8 inch Allen wrench, and the fitting is built for use with 1 inch outer diameter rail tubing, with a stainless tube wall thickness of 0.049 inches for the tubing it connects to.

The 290901-1 is part of Sea-Dog's Rail Tees, Elbows and Bow Forms line, a family of hinged, universal, and left/right handed tee, elbow, and corner fittings engineered to work together across a boat's hand rail system. Set screws for this fitting family can also be purchased separately under part number 299999-1 if replacements are needed.
