Adjustable underfloor boxes are available at eibabo in the catalog of underfloor systems for the installation of cables and lines. The adjustable box is needed for the creation of an inspection opening for cable ducts as well as for installation in a raised and cavity floor. You can find height-adjustable boxes in different nominal sizes. There are height-adjustable boxes that differ in design (round / square), the number of device boxes, types with cord outlet for the installation of devices and the possible height adjustment. Adjustable boxes are ideal for the installation of devices in wet-cleaned floors, for installation in mounting holes in screed-covered channel systems and in raised and cavity floors or even for use in dry rooms with dry-cleaned floors. The height of the adjustable boxes can also be adapted to the floor level. Many box types are made of an impact-proof cord outlet with handle or an inserted steel lid and a box frame with integrated click ladder.
