Durable Marine Rail Flagpole Support Rod

This flagpole support rod measures 39.0 × 5.0 × 2.0 cm (15.33 × 1.97 × 0.79 in) and is manufactured exclusively from stainless steel — chosen for proven performance in ISO 9223 C5-M (marine) corrosivity classification zones. The component has no moving parts, hinges, or set-screws; structural integrity relies solely on material properties and geometric rigidity. Surface polishing serves dual purposes: improving visual cohesion with high-end marine fittings and lowering surface energy to inhibit biofilm adhesion. Compatible with standard flag grommets and lightweight polyester or nylon flags. Verified for use on vessels operating in sheltered waters, estuaries, and near-coastal zones — not rated for offshore or heavy-weather continuous deployment.
