Product Description: If you own stainless clad resin scuppers with a bright stainless steel flange and a black or dark grey interior, this Flapper and Mounting Ring Kit is the perfect repair solution to restore your boat’s drainage system. These scuppers commonly have a groove inside the flange about 3/4" inside the face of the scupper (Picture 4)that securely holds the mounting ring, onto which the flapper attaches via screws. Over time, the entire mounting ring and flapper assembly can blow out due to pressure or wear, compromising water drainage and vessel safety. This kit provides both the mounting ring and the flapper, offering a complete replacement for a secure, leak-free fit. If you only require the 1-5/8" flapper replacement but your mounting ring remains intact, consider part #PRE56677KT as a compatible alternative. Widely used on a variety of boats, this repair kit is ideal for owners needing a reliable fix for their stainless capped resin scuppers—especially when the flapper measures 1-5/8" across. Specifications Flapper Diameter: 1-5/8" (fits most stainless clad resin scuppers) Ring Diameter: ~1-7/8" Outer Diameter Material: Stainless steel clad resin with bright stainless flange and black/dark grey interior Includes: Flapper and mounting ring assembly Compatibility: Designed for scuppers featuring an internal flange groove about 3/4" inside the face of the flange to hold the mounting ring WARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.
