Whitecap 1" O.D. 30° Rectangle Base SS Rail Fitting

The Whitecap 1" O.D. 30° Rectangle Base SS Rail Fitting (MPN 6178C) is a marine-grade stainless steel deck fitting engineered for mounting railings, grab bars, and structural support systems on vessels, outdoor platforms, and tactical equipment installations. Built from 316 stainless steel—the corrosion-resistant standard for saltwater and harsh-environment applications—this rectangular base fitting delivers the reliability demanded by military, law enforcement, and maritime professionals who cannot afford equipment failure in the field or at sea.

This fitting features a 1-inch outer diameter rail socket with a precision-engineered 30-degree angle designed to accommodate angled deck layouts and non-perpendicular mounting surfaces common in vessel construction and tactical deployments. The rectangular base measures 3-1/4" x 1-7/8" and utilizes three #10 fasteners for secure through-bolt installation, distributing loads evenly across the mounting substrate. The 316 stainless steel construction resists pitting and stress corrosion cracking even in high-chloride environments, making it suitable for saltwater vessels, coastal installations, and long-term outdoor exposure without degradation or maintenance-intensive surface treatment.

This rail fitting is ideal for marine architects, ship fabricators, and tactical equipment specialists who specify durable deck-mounted systems for military vessels, patrol boats, and permanent outdoor platforms. Installation requires three evenly spaced #10 holes drilled through the mounting surface; bolts (sold separately) should be marine-grade stainless steel or equivalent to maintain corrosion resistance. The 30-degree offset allows seamless railing continuation on cambered or sloped decks, eliminating unsightly gaps and ensuring personnel safety in high-motion environments. Weight of 0.55 lbs makes it suitable for applications where load distribution across multiple fittings is preferred over single heavy-duty bases.
