Product Info

Gravity Grille Black

Plastic construction gravity grille for air extraction.

4” / 100mm male round spigot on the back of the grille makes it quick and easy to install into 100mm duct work.

Shutters on the grille close automatically when not in use, ensuring no back draughts through the vent, also helps to prevent noise pollution odours from outside whilst stopping anything from flying or crawling into the ductwork.
