This VENT is fitting the side box hole of Sondors's box, to cool down the controler with fresh air.
No modification on the box have to be made. (it comes in place of the rubber cap)
The vent can be turned down in case of rain > no trace/scratches on the box thank's to a small leveler sepation.
The ring has to be glued (with locite glue) on the main part.
Then the 6 small part can be fixed with small screws.
Enjoy it !
