Whitecap 1" O.D. 45° Rectangle Base SS Rail Fitting

The Whitecap 1" O.D. 45° Rectangle Base Stainless Steel Rail Fitting is a precision-engineered stainless steel component designed for secure rail-to-deck mounting in marine, industrial, and tactical applications. Manufactured from 316 stainless steel—the corrosion-resistant alloy standard for saltwater and high-humidity environments—this rectangular base fitting provides a stable connection point for 1-inch outer diameter rail systems at a 45-degree angle, making it ideal for equipment racks, cable runs, antenna mounts, and modular platform configurations on vessels, vehicles, and tactical structures.

The fitting features a 3-1/4" × 1-7/8" rectangular base with four 1/4-inch fastener holes, enabling distributed load attachment across a wide footprint and multiple anchor points. The 45-degree angle orientation allows for diagonal bracing and angled rail runs, improving structural rigidity and load distribution compared to perpendicular mounts. Constructed entirely of 316 stainless steel, this fitting resists rust and corrosion in salt spray, freshwater, and harsh chemical environments—critical for maritime, offshore, and coastal tactical operations where ferrous metals fail rapidly. The Whitecap 6115C design complies with standard rail specifications used across marine hardware, military vehicle systems, and modular weapons platform architectures.

This rail fitting serves operators, equipment installers, and maintainers who require corrosion-proof structural connections for angled rail configurations. Common applications include deck-mounted equipment on patrol boats and offshore platforms, tactical vehicle rail systems requiring angled support, modular weapons platform construction, communications antenna mounts, and load-bearing cable management systems. The rectangular base design distributes stress across four fastener points, reducing the risk of failure from shock loads, vibration, or dynamic movement common in marine and mobile tactical environments. At 8.9 ounces, the fitting remains lightweight while maintaining the robust material composition required for professional-grade mounting infrastructure.
