Adjustable Vent Anodised Aluminium (Hither Green SE13)

satin anodised aluminium airbrick vent cover. For openings up to 229 mm x 52mm. designed to fully cover double brick aperture. suitable for interior/exterior fresh air ventilation and warm air systems. This was purchased for our bathroom, and then it turned out we didn't need it as the decorator fitted a new one. It has been hidden in my loft for ages and I came across it while having a clear out. Still in its sealed wrapper and like new.
