Kaiser 1555-26 UP Device Connection Box. This flush-mounted program for electrical installation elevates the flush-mounted installation to a new level and makes it easier than ever before. With 25% more installation volume compared to conventional flush-mounted device connection boxes, it comfortably accommodates wires, connection terminals, and built-in devices. The quick fixation using clamping ribs in all materials allows for up to 50% time savings during installation without plaster. The neutral and stable combination enables quick multiple combinations with a 71 mm center distance. Thanks to open wiring and a breakable separating wall, device connections can be made without spatial separation. Pre-wired devices, especially sockets, can be installed particularly quickly and easily. The low entry points and low wiring maximize usable wiring space and facilitate the installation of built-in devices due to the low-lying cables. The device mounting is made as simple and flexible as never before, thanks to expansion claw fields and 4 x 3 screw domes. The plaster compensation frame allows for continuous plaster leveling from 10 to 35 mm with just one accessory.
