The UP¹ Fix flush-mount boxes are designed for maximum installation speed: With their ribbed clamping mechanism, they can be secured in any wall structure without plaster or PU foam-saving up to 50% of installation time. A 25% increase in installation volume creates more space for wires, terminals, and devices. In addition to the advantages of the entire UP¹ family-such as open wiring, entry points near the bottom, and side-independent combinations, additional features and accessories-such as the plaster compensation frame with stepless adjustment from 10 to 35 mm-ensure a convenient installation. https://elecena.pl/product/30452513/1055-06-device-plug-up-fix-t-46-millimetres 2026-06-28 https://elecena.pl/product/30452513/1055-06-device-plug-up-fix-t-46-millimetres 2026-08-31
