316 Stainless Steel Four-Way Cross Fitting for Marine Handrails
The316 stainless steel four-way cross fitting is a marine tube connector designed to join handrail and railing round tubes on yachts and ships. This stainless steel tube cross connector is available in 22mm, 25mm and 32mm tube sizes and features a mirror-polished surface for corrosion resistance and a clean, high-end finish. It fits by slip-on connection secured with lock screws, requiring no welding during installation.
What Is a Marine Four-Way Cross Fitting?
Afour-way cross fitting is a pipe/tube connector with four openings arranged in a cross pattern, allowing four round tubes to meet and be joined at a single point. In marine applications it is commonly used for handrail,railingandguardrail structures on yacht decks, vessel sides, cabin walkways and gangways. The"seat"(slip-on) type fits over the outside of the tube and is fixed by lock screws, providing a stable, tool-friendly connection suitable for non-load-bearing rail systems. Made from 316 stainless steel, it is selected for its resistance to saltwater and chloride attack in the marine environment.
