For assembly, a plastic sheet is punched with the extended ISO 838 4-hole format (also known as “888” or “3 × 8”) and the corresponding holes are clipped into the anchors of the frame [11]. After usage, the plastic sheet can be thrown away while the frame can be disinfected

The distance of the visor to the head has been increased to make it comfortable to wear FFP-Masks. The floor in the area of the forehead rest was removed to increase wearing comfort. 1: Anchors for attaching the plastic sheet. 2: Brackets that hold the visor directly against the base part on the edges. 3: Tight loop at the end to hold the elastic band reliably. 4: Interfaces were added in order to install possible extensions (e.g. increased forehead rest)
