Replace your old worn-out flapper scupper with our new Flow-Max™ positive sealing ball scupper. A larger exit hole allows 70% more water drainage than its nearest competitor. Multiple mounting holes make retrofits quick and easy - no filling holes or re-drilling. A neutral buoyancy ball ensures the ball won't float up and break the seal. Meets all ABYC standards.
The easy twist-off design makes cleaning debris a snap. Simply twist counterclockwise to remove the ball cavity, clean out and twist back on. Stainless steel security pin provided for added safety.
