It uses a durable thermo-plastic flapper engineered to resist curling and warping from sun exposure and chemical contact, so the flapper keeps its shape and maintains a secure seal trip after trip. The flapper is finished in black and sits inside a white frame for a clean, finished look on deck.\u003c\/p\u003e\u003cp\u003eInstallation is straightforward: the assembly mounts over an existing drain tube or connects directly to a 1.5 inch thru hull using just four screws. It is compatible with drain tubes ranging from 1 inch up to 1.25 inches, which covers a wide range of boat setups, and its grooved interior is designed to fit securely over drain flanges for a watertight seal. The hole pattern is also designed to support retrofitting other manufacturers' rubber flapper assemblies, making the SA-2B a practical replacement option when an existing scupper flapper has failed.\u003c\/p\u003e\u003cp\u003eWith one port and a flush mount design on both the inlet and outlet, the SA-2B is intended as a simple, reliable drain valve upgrade for boats needing dependable self-bailing performance without unwanted water intrusion.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e T-H
