Performance & Real-World Benefits
The flapper scupper repair kit will take care of any flapper replacement job. The traditional flapper scuppers use molded rubber flappers that curl and deform over time, requiring replacement to prevent leaking. The flappers are not rubber, but are molded of a thermoplastic elastomer that is resistant to UV and the elements, so they do not curl like the rubber flappers. Repairs most scuppers with flappers, regardless of manufacturer. Kit contains all parts needed to repair 2 scuppers of a given size.
