Sea-Dog Line 4-Way Rail Tee Fitting 293141-1, 1 Inch Tube OD, 316 Stainless Steel

The Sea-Dog Line 293141-1 is a 4-way rail tee fitting designed to create directionality where handrail tubing sections meet at a junction, letting you branch a 1 inch outside diameter rail run in four directions from a single point. It is constructed of investment cast 316 stainless steel for corrosion resistance in marine environments, making it suitable for lifeline, grab rail, and bow rail applications aboard boats and other marine craft. The fitting includes set screws where appropriate to lock the tubing in place once inserted; replacement set screws are available separately under part number 299999-1 if needed. Installation requires a 1/8 inch Allen wrench to tighten the set screws and secure the tubing sections into the fitting body. The fitting is sized for tube with a wall thickness of 0.049 inches, so it is intended for use with standard-wall 1 inch OD stainless rail tubing rather than heavier-wall tube. Overall dimensions are 3.25 inches by 3.25 inches. This 4-way tee is one of several rail tee, elbow, and bow form fittings offered in the same investment cast 316 stainless steel line, allowing a rail system to be built with matching hardware throughout.
