Sea-Dog 3-Way Corner Fitting, 7/8 Inch Tube, 316 Stainless Steel Boat Rail Hardware

The Sea-Dog 3-Way Corner Fitting (293100-1) is a handrail connector designed for 7/8 inch tube boat rail systems, joining three rail sections at a corner to create clean, secure directional changes in a rail run. It is machined from investment cast 316 stainless steel, giving it strong corrosion resistance for saltwater and marine environments while matching the finish of other Sea-Dog rail hardware. The fitting includes set screws where appropriate to lock it onto the tube ends, and installation is done with a 1/8 inch Allen wrench. It is sized for tube with a wall thickness of 0.049 inch. If additional or replacement set screws are needed, they are available separately under Sea-Dog part number 299999-1. This fitting is intended for boat builders, canvas and rail fabricators, and boat owners repairing or customizing bow rails, stern rails, and other tubular handrail systems. At 0.47 pounds, it is a compact, durable component that keeps a three-way rail junction rigid without adding significant weight to the rail assembly.
