Product Information

The FF109-FRSC I Hour Fire Rated Speaker Cover is a dome-shaped intumescent cover which has been specifically designed to help maintain the integrity of fire-resistance rated ceilings for 60 minutes when penetrated by in-ceiling loudspeakers.

The unique design gives architects, sound professionals and installers more freedom in speaker selection as the covers are suited to a wide range of speaker sizes up to 10″.

The flexible and lightweight nature of the covers makes installation quick and easy, reduces the stress put on the ceiling and significantly reduces labor costs compared to standard dry-walled box constructions.

The sound absorbing properties of the proprietary intumescent material enhance the acoustic performance of the structure for a crisper and clearer sound.

The high expansion and insulating properties of the cover ensures that both, flame spread and heat transmission, are stopped for 60 minutes.

Inside Height 8″
