kProduct Description Enhance onboard safety with this Large Marine Fire Extinguisher Port, designed for rapid emergency response and easy installation. Ideal for boats, yachts, or engine compartments with limited access, this port allows you to deploy a portable fire extinguisher safely and effectively without opening the engine hatch—a must-have for fire safety preparedness. Featuring a wide 3-¾″ opening, it's perfectly suited for fire extinguishers with larger nozzles. The 316 marine-grade plastic construction resists UV, corrosion, and saltwater exposure, while the integrated O-ring seal prevents water intrusion into the engine compartment. This port installs in minutes with a simple 4" hole cut—just push the flange and tailpiece into place. The low-profile flange minimizes snagging and blends seamlessly with most gel coat finishes. Compliant with American Boat and Yacht Council (ABYC) and ISO safety standards, this product has been trusted by major boat builders for years to protect vessels from the catastrophic risks of engine fires.
