Stainless Steel Rectangle Base 90° – AISI 316 Boat Rail Fitting is a marine railing component designed to connect a vertical round tube to a flat mounting surface at a 90-degree angle. Its rectangular base provides a practical mounting footprint for use on boat decks, gunwales, cabin tops, and other suitable flat surfaces. This fitting is commonly used when assembling or replacing handrails, guardrails, support rails, stanchions, and other tubular railing structures on boats and marine vessels.

Manufactured from AISI 316 stainless steel, this boat rail base is suited to marine installations where hardware is regularly exposed to moisture, saltwater spray, and outdoor conditions. AISI 316 stainless steel is widely selected for marine handrail fittings because of its corrosion resistance, durability, and clean appearance. The smooth, polished finish complements other stainless steel railing fittings and surrounding deck hardware, making the component suitable for both new railing installations and maintenance projects.

The 90-degree tube socket holds the rail in an upright position relative to the mounting surface. Four countersunk mounting holes are arranged across the rectangular flange, allowing suitable fasteners to sit neatly within the base. The tube socket also includes side fixing points for securing the inserted rail tube. Correct fasteners and installation methods should be selected according to the mounting surface, tube specification, and requirements of the vessel. Before ordering, buyers should confirm the outside diameter of the existing or planned rail tube.

Two variants are available for widely used marine tube sizes. Product code 80070-01 accepts a 7/8-inch (22 mm/22.2 mm) tube, while product code 80070-02 accepts a 1-inch (25.4 mm) tube. This choice makes the railing flange useful for several boat handrail and stanchion configurations. The fitting may be selected for building a new railing system, replacing a worn boat rail base, or matching an existing tube assembly, provided the angle, tube diameter, and mounting arrangement are compatible.

As a fixed 90-degree marine handrail fitting, the product helps create a stable connection point between the tubular rail and the mounting surface. Its rectangular profile can be useful where a longer base shape is preferred for positioning the mounting holes. Installation areas should be flat, sound, and capable of supporting the intended railing application. Periodic cleaning with fresh water and suitable stainless steel care products can help maintain the fitting’s polished appearance, particularly after exposure to saltwater.
