The low-profile connection box SLIM BOX 75x2 enables the installation of diffusers in a space of only 14 cm (from the ceiling to the surface of the plaster ceiling). The box is suitable for 125 mm connection diffusers.

This is especially relevant when it is desired to lower the plaster ceiling to a minimum.

The box is installed on the ceiling like a standard junction box. Then the diffuser is inserted into the box connection duct and plasterboards are screwed.

The connecting duct of the SLIM BOX box is 2 cm long. So you can adjust the installation height within 14 - 16 cm.

Duct connection flanges have EPDM sealing gaskets.
