Split-Type Boat Deck Floor Drain is a specialized marine hardware component designed for yachts, fishing boats, and other watercraft. Unlike standard one-piece drains, it features a two-piece detachable design where the top grating cover can be unscrewed or removed from the lower drain body without any tools. This setup allows boat owners to easily clean out trapped seaweed, sand, fish scales, or bait debris right on the deck, preventing clogs in the drainage hoses.
Because space is often limited near the gunwale or in shallow deck areas, these drains are frequently paired with a 90-degree elbow design and a barbed tailpiece to save vertical space.
Key Technical Specifications
* Material: Must be marine-grade 316 stainless steel. Compared to 304 stainless steel or plastics, 316 provides maximum resistance to pitting and crevice corrosion in harsh, high-salinity saltwater environments. It is typically finished with a high-end mirror polish.
* Common Hose Diameters:
• 32mm (1-1/4 inch) O.D.: Ideal for tight spaces or smaller boats with low-volume drainage needs.
• 38mm (1-1/2 inch) O.D.: The most common standard size in the marine industry, fitting most mid-sized fishing boats and center consoles.
• 50mm (2 inch) O.D.: Heavy-duty size optimized for large open decks or livewells requiring fast water evacuation.
To ensure you get a replacement that perfectly matches your current setup, could you let me know:
1. What is the inner diameter (ID) of your existing drainage hose? (e.g., 1-1/4", 1-1/2", or 2"?)
2. Do you need a 90-degree elbow for tight clearances, or a straight vertical drain?
3. Are you looking for a model with a built-in rubber check valve to stop saltwater backflow, or just a standard open drain?
