These feature PVC boxes with an inspection hatch located inside the premises on the back or bottom of the box. 

The top-mounted roller shutter system can be fitted with a mosquito net built into the roller shutter box. This ensures the roller shutter and the mosquito net can be operated independently. A variant where the integrated mosquito net system has been placed under the roller shutter slats in order to bring it closer to the window frame is available.

Box flush-mounting options:

• on the outside
• on the inside
• on both sides

Installation:

• in a window opening together with the window
