Efficient installation and increased reliability thanks to innovative two-part design

The flush-mounted junction box (Art.-No. 9907.20) offers a variety of advanced features, making it an ideal choice for electrical installers. A key characteristic of this innovative product is its two-part design, which facilitates optimal alignment and installation. The front part can be easily nailed onto the formwork, ensuring precise positioning. The other part is then simply snapped onto the front part. Other features that are designed to meet the requirements of modern installation work include the sixteen M20/25 combination entries and four M32/40 combination entries for flexible corrugated plastic conduits.

Processing instructions

Align and fix the front part to the formwork using the four pre-installed nails.
