Sleeve Block Grille

FPC (UK) Ltd offers Sleeve Block Grille. Where a cavity exists in side of a wall then a block grille is normally placed each side of the cavity. Alternatively the cavity should be framed or enclosed to set only one block grille centrally in the duct. We have done away with the need to enclose the cavity by mounting the block grille in a metal sleeve so reducing material cost and fitting time.
