Stainless capped resin angled thru hull scupper 1 1/2", short threads

Product Description

Upgrade your boat’s drainage system with our 15-Degree Angled Thru Hull Scupper, expertly engineered to combine toughness, functionality, and style. Molded from durable fiberglass reinforced resin, this scupper withstands the demanding saltwater marine environment while remaining lightweight and cost-effective compared to stainless steel alternatives.

The scupper’s polished 304 stainless steel cap is ultrasonically welded to the outer flange, offering an elegant, high-end finish that protects against sun and saltwater damage — common concerns with traditional plastic thru hulls. This premium design is trusted by many saltwater boat builders for its superior reliability and marine-grade durability.

Designed to fit transoms up to 1-1/4" thick, this thru hull scupper features a hose barb compatible with 1-1/2" ID marine hoses, ensuring broad compatibility with various boat setups. Installation is quick and simple, aided by an included mounting nut for secure fitting.

A built-in recessed flapper, measuring 1-5/8" in diameter, guarantees efficient water drainage while effectively preventing backflow, protecting your vessel from unwanted water intrusion.
