An optional matching reverse flange is available to give a neat appearance on both sides of the door or partition.
Suitable for low or high level mounting requirements.
Fixings are via countersunk screw holes in the border. Free area approx 40%.

Mill Finish: Please note that 'mill finish' means untreated aluminium and is useful if you wish to provide your own finish. A 'mill finish grille' may naturally have light scrapes and abrasions from the manufacturing process. We can polish the scratches out if no finish is to be applied. This finish is referred to as "polished aluminium".
