One of the best-looking, long-lasting, toughest Scuppers on the market. The Scupper Flap is tough, flexible material with a molded V-groove to reduce backwash. Fasteners are concealed and corrosion-proof. For 1-1/2" ID exhaust hose and transoms to 3" thick.
Rugged Stainless Construction
Cast from certified #316 Stainless Steel alloy for strength and lifetime corrosion-resistance.
We polish all visible areas to a mirror finish, then send each part through passivation for additional protection.
Thick steel sidewalls withstand continual stress and hose flexing.
Faster, Simpler Installation
A channel under the flange holds a bead of sealant, making it easier to apply a trouble-free seal.
All sizes have wrench flats to hold as a gripping surface. One installer can tighten all connections from inside the hull.
Barbed tail ends provide plenty of room to hold multiple clamps.
