Scupper Flapper Repair Kit



  • Constructed of thermoplastic elastomer
  • Do not curl like rubber flappers
  • Repairs most scuppers with flappers, regardless of manufacturer
  • Kit contains all parts needed to repair 2 scuppers

Our 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. Our 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. Each kit contains 2 each of: 1 1/2"flappers and 1 3/4" flappers, and all necessary keepers and fasteners.

Too many flaps

They work fine. I wish I could have just bought the sizes I needed to replace.

Good Product, Bad marketing

The scupper flappers fit and work fine, five stars for that. The reason for the three stars is: I only need the 1-5/8" flappers yet I am forced to buy two other sizes that I don't need.. I have trimmed the larger ones down and used them. However, I shouldn't have to do that.
