Delivered-cost tip: Small marine hardware is often more cost-efficient to ship with the other fittings needed for the job. Final shipping is calculated at checkout for the complete cart and destination.
Questions
Can the vent be closed?
The butterfly mechanism is adjustable. Review the gallery for the open and closed positions and do not rely on it as a watertight closure.
Which size should I order?
Use the dimension image and measure the available surface and opening; the nominal diameter alone is not enough.
