This large fire extinguisher port installs in minutes and greatly lessens the risk of injury due to engine fires. Just a quarter turn to open or close for easy access through the 3-3/4" opening. Includes an O ring seal to prevent water intrusion. Ideal for fire extinguishers with larger nozzles! The mounting flange just pops into a 4" hole, no fasteners required. Flange is very flush to avoid catching on lines, toes, etc. Slightly off-white color blends with most gel coats.
If a fire is suspected, just push the nozzle of your portable fire extinguisher through the opening and discharge per extinguisher instructions.
Complies with American Boat and Yacht Council and ISO regulations.
Made in the USA!
To install, just cut a 4" hole into the engine compartment (where it is easily accessed). Push flange & tailpiece into hole using the impact barbs to hold it in place (it will be a tight fit!). Port is sealed, keeping moisture and dirt out of the engine compartment and noise & fumes in the engine compartment.
