I would like hang three 60cm wide IKEA kitchen cabinets on a plasterboard wall but find that there is very little wood behind the plasterboard. There are two vertical battens, 30mm wide and 38mm deep at 3 feet and 6 feet from an external wall that I wish to start the cabinets at. The wall consists of two sheets of 12.5 mm plasterboard separated 38 mm apart by the vertical wood. When the base units were removed, the vertical battens were identified at the bottom of the wall where the plasterboard doesn't reach the (concrete) floor. Also visible at the bottom is a horizontal batten nailed to the plasterboard with a gap of about 6 cm between the ends of the horizontal wood and the verticals. Skirting boards are nailed to this - with no skirting behind the base units. I currently have one wall cabinet flanked by two floor standing cabinets, By poking the plasterboard there appers to be hioizontal battens at the top and bottom of the wall cabinet but these horzontal pieces of wood do not span to the verticals. The total width of the wall is 63mm. I suspect that the wall is constructed of cellular wallboard.
As the angle brackets for the three wall cabinets can't all be fixed to the secure(??) vertical pieces of wood, does anyone have any sugestions on the best way to hang the cabinets such that they won't fall off? [The bottoms of the verticals have a slim piece of metal on them - possibly attached to the floor inder the wood - but that is not visible]
Many thanks,
Mike Robinson
