Build custom handrails without welding. West Marine handrail fittings let you build rigid bow, stern and cabin top handrail and lifeline systems, providing secure handholds and/or rigid barriers around your boats perimeter. Made in a variety of shapes and angles, these components can accommodate the many configurations possible on a boat. They are available in two diameters: 7/8" dia., generally used on smaller powerboats, and 1" dia., used on sailboats and larger powerboats. Most of our rail fittings are made 316 stainless steel to provide superior corrosion resistance in saltwater and fresh water environments. Other fittings are constructed of Zamak, a copper, zinc aluminum alloy. Zamak fittings are chrome-plated with a polished finish to provide corrosion resistance suitable for freshwater applications. We recommend matching materials between system components to minimize the effects of galvanic corrosion between dissimilar metals. For safety, rails fittings should be thru-bolted to the deck, using substantial backing plates. While it is tempting and convenient to use sheet metal screws, machine screws with locking nuts will be far stronger. Plenty of sealant around the fastener holes, especially on the shanks of the fasteners, will help prevent leaks and water damage to the hull material. And a small dab of Blue Loctite on the set screws will ensure that your railing stays together for many seasons.
