Thanks to its depth of 49 mm, the halogen-free and airtight Qnect cavity wall box for drywall construction is ideal for narrow wall constructions. With a diameter of 74 mm, the device plug offers significantly more junction space than conventional installation boxes. For multiple combinations, the switch boxes in wooden frame walls or rigid plaster can therefore also be firmly connected to each other at a standardised spacing of 71 mm. The SCS connection technology with large-area connection membrane including cable-popping technology then enables simple through-wiring without connection sockets. For installations with sound insulation, we recommend the Qnect cavity wall socket sound insulation. Both versions are also available with a depth of 62 mm. https://elecena.pl/product/29227841/p200-01-qnect-cavity-wall-device-plug-49-mm 2025-08-05 https://elecena.pl/product/29227841/p200-01-qnect-cavity-wall-device-plug-49-mm 2025-12-16
