Height Tables

Standard louvre height (ht)for 152mm blades can be computed as follows:

ht= (nb x 139.7) + 25.4

3

where: ht= height of frame

nb= number of blades



Height Tables

Standard louvre height (ht) for 102mm

blades can be computed as follows:

ht= (nb x 88.9) + 25.4

4

where: ht= height of framenb= number of blades
