Sea-Dog Hinged Rail Tee Fitting, 316 Stainless Steel - Available in 7/8" and 1" Tube, 60 and 90 Degree Angles

The Sea-Dog Hinged Rail Tee is a cast 316 stainless steel fitting that lets you branch a handrail run at a fixed angle while allowing the joint to hinge and fold flat for storage, docking, or boarding access. Investment cast for a smooth, corrosion-resistant finish that matches other Sea-Dog rail hardware, this tee accepts tube on all three legs and is secured with set screws tightened through a 1/8 inch Allen wrench. It is built for the marine environment, standing up to salt spray and UV exposure without pitting or discoloring like lower-grade stainless.

Use it anywhere a handrail needs to branch off the main line at a set angle - bow rails, gate openings, ladder access points, and T-top or bimini frame junctions - while retaining the ability to fold the branch out of the way when not needed.

Sizes & Options

This tee is sold in three configurations combining angle and tube diameter. First measure the outer diameter of your existing rail tube (7/8 inch or 1 inch) with calipers or a tape measure, since the fitting must match the tube size exactly for the set screws to seat properly. Then decide whether you need a 60 degree or 90 degree branch angle based on the geometry of the rail run you are joining - a 90 degree tee is typical for a straight side branch, while a 60 degree tee suits a more angled or swept branch line. Match your tube diameter and desired angle to the options below to select the correct SKU.
