Non-vision door transfer grilles are two piece grilles designed to be installed in doors or partitions. They allow free movement of air but allow no sight of one side from the other. They are supplied with an additional frame that affords a smart finished appearance on both sides. The use of the additional frame is optional. Fixing screws are included.
Sizes stated refer to the aperture size i.e. the opening they are designed to fit. Add 44mm for overall size (including flange).
