Hey boat and RV owners, this is a total game-changer for your deck or cockpit! These Marine City cup holders are made from super durable, polished stainless steel that resists corrosion and looks sleek. Each one has a cool red LED light (runs on 12V, 1W) that adds a nice glow at night—perfect for evening cruises or poker games on board. They measure about 3-1/4 inches tall, with a 4-1/4 inch flange and a 3/8 inch barb. The center drain lets spills escape easily, so no more soggy cup holders. Installation is a breeze: just drop them into any standard hole on your table, dashboard, or countertop. You get a set of 4, which is awesome for stocking up or outfitting multiple spots. Whether you're on a yacht, kayak, or just want to upgrade your RV interior, these holders are practical, stylish, and built to last in tough marine environments.
