Vent Ports - 2 Pack

These plastic canvas vent ports can easily be installed into your existing boat canvas cover / play pen cover. Your boat canvas aluminum extension support poles will slide into the vent port bottom receiver sleeve, for a more stable canvas support. Vent ports were designed to let your boat canvas and boat interior automatically ventilate while keeping the rain and weather out. Vent ports will help eliminate build up of moisture and condensation that will lead to mold and mildew, then rot. Protect you investment! In need of the poles also-see our three styles of poles. This price is for the 2 pack.
