The grille can be delivered with a connecting plenum to the circular duct, with horizontal or vertical connection.
The plenum is provided with suspension elements (lugs) and bead roll on the spigot, for easy fixing of the flexible duct.
For hidden mounting the grille can be equipped with a mounting frame (CC).

The plenum is available in two options, uninsulated or insulated with 6 mm thick elastomeric rubber.
Mounting frame (CC)
The mounting frame is used when a hidden, easy and fast installation of the grille is desired. Depending on the size required, it is made and delivered in one or more pieces.
As standard, the grille is mounted by screws.
Optionally, for a hidden and easy assembly, a mounting frame can be used. The installation of the grille in the mounting frame is done by clamping.
