Sea-Dog Stainless Steel Stud Mount Flanged Handrail, 10 Inch, Part 254209-1

The Sea-Dog 254209-1 is a stud mount flanged handrail built from formed 304 stainless steel, giving boaters a secure, corrosion-resistant grab rail for decks, gunwales, companionways, and other onboard grip points. The flanged base provides a larger mounting surface than a standard end-cap rail, which adds stability while keeping the look clean since the design uses no visible mounting hardware. Two integral 5/16 inch-18 x 1-5/8 inch threaded studs are formed directly into the base, so installation is a matter of drilling through-holes, passing the studs through, and securing them from the underside with two 5/16 inch-18 nuts (nuts not included). The rail measures 10 inches overall (dimension A) with an 8-3/4 inch dimension B, a 2-1/4 inch dimension C, and a 1-1/2 inch dimension D, and the tube itself has a 7/8 inch outer diameter for a comfortable, secure hand grip. At 0.44 pounds, it is light enough for easy handling during installation but retains the rigidity expected of formed stainless tubing. Because it is finished in stainless steel rather than a coated or painted finish, it resists saltwater corrosion and holds up to sun and spray exposure over time. This handrail is a direct fit replacement or upgrade wherever a 10 inch stud mount flanged handrail of this footprint is needed.

What material is this handrail made from? It is formed from 304 stainless steel, which resists corrosion in saltwater and marine environments and is left in a stainless finish rather than painted or coated.

How does this handrail mount to the boat? The 254209-1 is a stud mount design with a flanged base and two integral 5/16 inch-18 x 1-5/8 inch threaded studs built into the rail, so there is no visible mounting hardware on top of the surface.

Does this handrail come with mounting nuts included? No, the two 5/16 inch-18 nuts needed to secure the 254209-1 to its mounting studs are not included and must be sourced separately.
