Description

The 210 × 210 mm overpressure grille from the quality brand Renson is made from AIMgSi 0.5 aluminium profile and finished in RAL9005 black, without insect mesh. The louvres are mechanically linked and open and close together to reduce noise. They sit within the aluminium frame, preventing wind from moving them when the louvres are closed (under normal weather conditions). The grille is supplied with screws and plugs and features concealed screw fixings. The build-up height is 29 mm.
