Sea-Dog 60 Degree Rail Tee Fitting, Left (Port), 7/8 Inch Tube, 316 Stainless Steel, Part 291600-1

The Sea-Dog 291600-1 is a 60 degree handrail tee fitting built for the left (port) side of the boat, sized for 7/8 inch outside diameter rail tubing. It is machined from investment cast 316 stainless steel, giving it strong corrosion resistance in saltwater and marine environments while holding a clean, polished look that matches the rest of a boat's stainless rail hardware. This tee creates the directional change needed where handrail tubing meets at a 60 degree angle on the port side, and it is designed for use with inside set screws to lock the tubing securely in place.

Installation uses inside set screws and requires only a 1/8 inch Allen wrench, making it straightforward to fit during a rail repair or a new rail build. Set screws are included with the fitting where appropriate for the connection; replacement set screws are also available separately as Sea-Dog part 299999-1 if extras are ever needed. The fitting is built from tubing stock with a stainless wall thickness of 0.049 inch, consistent with the rest of Sea-Dog's rail tee, elbow, and bow form line.

Because this is a port-side (left hand) 60 degree tee, it is not interchangeable with the starboard version. Buyers needing the right (starboard) equivalent in the same 7/8 inch size should order Sea-Dog part 292600-1 instead, as that is a separate, mirrored SKU.
