An intumescent air transfer grille measuring 112 x 225mm, designed for installation in fire-rated doors and partitions. The compact rectangular format suits narrower door stiles and applications where a smaller ventilation aperture is specified. The intumescent material expands under heat to seal the grille opening, maintaining the fire integrity of the door for the rated period while allowing normal air transfer during everyday use.

Supplied as a single grille.
