• Water drains through the scupper
• Ball closes when water stops flowing
• Prevents backflow from waves or wake
• Self-operating – no manual intervention needed

Applications:

• Cockpit sole drainage
• Deck scupper drains
• Transom drainage
• Self-bailing cockpit systems
• Above-waterline deck drains
