With a depth of 62 mm and a diameter of 74 mm, the halogen-free and airtight Qnect hollow wall box for drywall offers significantly more clamping space than conventional installation boxes. In multiple combinations, the device connection boxes can be firmly connected in wooden stud walls or drywall at the standardized combination distance of 71 mm. The SCS connection technology with a large-area connection membrane, including Cable-Plopp technology, allows for easy wiring without connection fittings. For installations requiring sound insulation, we recommend the Qnect hollow wall box for sound protection. Both variants are also available with a depth of 49 mm.
