Whitecap 1" O.D. 90° Rectangle Base SS Rail Fitting

The Whitecap 1" O.D. 90° Rectangle Base SS Rail Fitting (MPN 6141C) is a precision-engineered stainless steel deck rail component designed for securing and routing equipment, cables, and accessories on vessels, platforms, and modular tactical systems. Built from 316 stainless steel—the corrosion-resistant alloy of choice in harsh maritime and field environments—this fitting serves operators who demand durability under salt spray, moisture exposure, and extended outdoor deployment. Whether you're assembling a shipboard installation, building a portable tactical frame, or outfitting a coastal operations base, this right-angle rectangular base fitting provides the structural integrity required for professional-grade applications.

The fitting's 90-degree angle orientation allows perpendicular rail mounting, enabling efficient cable management and load distribution across deck or panel surfaces. With a 1-inch outer diameter tube connection and a 3-1/4" × 1-7/8" rectangular base footprint, the fitting accommodates 1/4-inch fasteners (typically four anchor points for maximum stability). The 316 stainless steel construction resists pitting and stress-corrosion cracking better than 304-grade alternatives, making it ideal for saltwater environments, humid climates, and applications where long-term material reliability is non-negotiable. Its 0.5-pound weight and compact profile minimize system load while maintaining the strength required for heavy-duty restraint and routing applications.

This rail fitting is commonly specified by maritime professionals, military logistics coordinators, and tactical equipment integrators assembling modular systems that demand corrosion resistance and repeatable installation cycles. Its rectangular base distributes fastening loads across a larger contact area, reducing stress concentration at bolt holes and extending service life in vibration-prone environments. Installation requires only basic fastening hardware and standard tools; the 1-inch diameter tube interface accommodates Whitecap and compatible rail systems. For operators sourcing deck hardware, cable management solutions, or structural components for coastal or field-deployed systems, this stainless steel 90-degree fitting delivers proven reliability and professional-grade materials engineering.
