Boat owners, listen up – this drain plug is a little lifesaver. Made by Five Oceans, it's designed specifically for a 1-inch diameter hole in your boat's hull (hole distance is about 1.5 inches). It's the screw-type, with tapered pipe threads and a rubber o-ring that makes sure the seal is watertight – no leaks. The cool feature? It's a captive plug, meaning it stays attached to the boat so you won't lose it overboard (we've all been there). The whole thing is crafted from tough, non-corrosive black nylon, so it won't rust or degrade in saltwater, and it's got a marine-grade rubber gasket for extra sealing power. Use it to drain water from the bilge or hull, especially when you're hauling the boat out or doing maintenance. It's a simple but essential piece of gear to keep your boat dry and ready. Five Oceans has been making quality marine stuff for 40 years, so you know it's reliable. Keep your bilge clear and your mind at ease.
