Product Description:

Upgrade your boat’s drainage system with our solid cast 316 stainless steel thru-hull scupper, engineered for superior durability, corrosion resistance, and reliable performance in the harshest marine environments. Featuring an internal flapper valve, this scupper effectively prevents water back-flow, protecting your vessel from unwanted water ingress while ensuring efficient drainage.

The highly polished stainless steel flange adds a sleek, professional finish to your boat’s transom, boosting both appearance and function. Designed with extended threads, this scupper easily fits thicker transoms, making it versatile for a wide range of boat configurations.
