Product description
Product description
Height-adjustable and decouplable square cassettes are suitable for flushfloor device installation in UGD-3 underfloor connection boxes. Depending on the design, they are suitable for dry, moist or wet-cleaned floors. The cassette rests on the fixing bracket fastened in the top frame of the box, using which the cassette can be adjusted to the top edge of the floor covering. The fixing bracket decouples the cassette from the raw ceiling. The connection socket must have an appropriate installation opening and, for this reason, needs a blanking lid with an appropriate installation opening. The cassettes are made from stainless steel or brass. All the cassettes contain a 4 mm thick sheet steel plate, for safe absorption of the traffic loads. Suitable cassettes are available for different floor covering thicknesses of 20 and 25 mm. Only suitable for smooth floor coverings.
