Sea-Dog Rail Base Fitting Rectangular Base 90° - 316 Stainless Steel - 1-11/16" x 3" - 7/8" O.D.

The Sea-Dog Rail Base Fitting Rectangular Base 90° in 316 stainless steel is a heavy-duty replacement component designed for marine and maritime applications requiring corrosion-resistant hardware. This fitting serves as a secure mounting point for railings, cable systems, and structural assemblies in salt-water environments, small craft rigging, and deck equipment installations. Built to withstand harsh coastal conditions, this rectangular base fitting delivers the reliability demanded by commercial vessels, naval installations, and recreational watercraft operators.

Manufactured from investment-cast 316 stainless steel, this rail base fitting offers superior corrosion resistance in chloride-rich marine environments compared to standard steel or lower-grade stainless alternatives. The 90-degree angled design provides perpendicular mounting capability, while the rectangular base (1-11/16" × 3") offers multiple fastening points for enhanced load distribution and structural integrity. The 7/8" outer diameter tubing connection accommodates standard marine railing stock, and the investment casting process ensures uniform density and dimensional consistency throughout the component, critical for load-bearing maritime applications.

This fitting suits vessel owners, maritime maintenance crews, and naval equipment specialists performing railing replacements, structural repairs, or equipment upgrades on boats, ships, and offshore platforms. The 316 stainless material remains maintenance-free in saltwater service, resisting pitting and stress corrosion cracking that can compromise lower-grade fasteners. Installation requires standard deck-mounted bolting through the rectangular base, compatible with existing Sea-Dog rail systems and OEM marine hardware configurations. Weighing just 0.45 lbs, the fitting integrates seamlessly into new builds or retrofit projects without adding significant weight to topside structures.
