T-H Marine DBS-2B-DP Duckbill Overboard Drain Scupper Black/White

The T-H Marine DBS-2B-DP is a tight sealing, one-way hull drain designed to prevent water backflow into your boat. This tough thermoplastic duckbill scupper provides a reliable solution for sealing under water pressure, making it ideal for marine applications where drain tubes sit at or below the waterline.

Key Features:

• Tough thermoplastic flapper seals tight under water pressure
• Easy to install over drain tubes with a universal hole pattern for replacing existing flapper scuppers
• Outer ring diameter: 2-3/4 inches
• Black/White color combination with black flapper and white mounting ring
• Universal hole pattern/size to replace flapper scuppers

This scupper valve is designed for boats, kayaks, and other watercraft that require reliable one-way drainage. The flexible thermoplastic flapper opens to allow water to drain out while automatically sealing shut when external water pressure is applied, preventing backflow into the hull.
