Flush-mounted boxes for solid wooden walls

- Suitable for solid wooden walls.
- Also applicable in hollow walls with a minimum plate thickness of 30 mm.
- Rock-solid mounting in wooden walls, thanks to unique wedge construction.
- Flush-mounting box specially developed for timber construction.
The innovative wedge construction ensures secure installation in solid wood and semi-solid walls with a panel thickness starting from 30 mm, such as OSB or fibre gypsum boards.

The box fits perfectly into a pre-milled hole of Ø 76 mm and is firmly anchored in the wooden wall. Just like the standard UHW50 box, the CLT version is suitable for multiple installations of switchgear. If required, the box can be easily dismantled and reused.

In addition to the standard UHW50-CLT box, a Perilex version is also available. Both variants are supplied in a fire-resistant edition. The inserts for airtight and/or soundproof applications can of course also be used with these UHW50 boxes.
