The Spelsberg cavity flat wall sockets have a low installation depth of 35mm and are therefore installed in thin walls. HW 040 is a hollow wall outlet box with 40mm depth. Wall outlet boxes are installed under plaster and are used to connect stationary equipment such as luminaires. In the Spelsberg range there are then two variants for lower panel thicknesses HW 050 and HW 065. The HW 050 built-in installation boxes (device boxes) are inserted into drilled holes of Ø 68 mm. They are equipped with sharpened, patented combination bridges. In addition to the individual cavity wall sockets, Spelsberg also manufactures cavity wall equipment double sockets. These are equipped with closed membrane lead-ins. The installer benefits from very fast installation: The box is snapped on and the connection of the device passes outside the can. Now the device and the connecting cable are inserted from above and the can is positioned. All you need to do is tighten the fixing screws - done!
