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

Our latest version of this product (Art.-No. 9907.30) also includes an integrated tunnel extension, supporting the trend towards efficient LED strip lighting in residential installations. This product offers all the benefits of the already successful 9907.20 series. The specially designed tunnel extension can accommodate LED strip lighting drivers up to a size of 230 x 50 x 35 mm. Especially in areas such as showers, bathrooms or corridors where LED lighting plays an important role, the flush-mounted junction box with tunnel extension offers an ideal solution. It enables electrical designers to easily incorporate LED strip lighting into their plans, as this item is specially designed for this purpose. It provides flexibility during the installation work on site while helping to ensure safety and reliability.
