SECURITY GRILLE TYPE ASG
Figure 16: Finishing protective grating type ASG
•
Wire or punch grid with a mesh size of ≤ 20 mm.
•
Intended use: mounting for one-sided connection.
•
Minimum distance a
min
= 50 mm from open damper blade
must be considered; if necessary, use extension part type
VT.
•
For H≥400, observe table 2 page 4.
