Description
A basic plastic mushroom vent with screw type opening and closing mechanism. Complete with a weather resistant rubber seal when fully shut and a grip handle to aid with opening and closing.
This vent is a very popular replacement for the original ‘Freeman’ boat mushroom vent.
When using this vent as permanent ventilation to comply with the Boat Safety Scheme (BSS) a spacer is required in the top (of approximately 25mm) to stop the vent from fully closing.
