Sea-Dog Stainless Steel Rectangular Rail Base Fitting - 30 and 60 Degree, 7/8" to 1" Tube OD

Sea-Dog rectangular rail base fittings anchor boat rail tubing to a deck, gunwale, or console at a fixed angle, giving you a clean, rigid connection point without the need for a swivel base. Each fitting is investment cast from 316 stainless steel for long-term corrosion resistance in saltwater environments, and the rectangular foot spreads load across the mounting surface for a secure, low-stress attachment. A set screw and Allen wrench installation let you lock the tube in place quickly during a rail repair or custom rail build.

This line is available in two fixed base angles and two tube diameters so you can match the exact geometry of your existing rail system or new fabrication.

Sizes & Options

Start by measuring the outer diameter of your rail tubing to confirm whether you need the 7/8 inch or 1 inch base, then choose the base angle that matches the mounting geometry of your rail run - 30 degree for a shallower rake or 60 degree for a steeper connection to the deck or gunwale. Measuring the existing fitting or tube before ordering will help ensure a correct match.
