Customer to specify A, B & C. Please note that options are limited by the fact that
A = C & A ≥ B

The branch determines the length L1. The duct entry can only be fitted to straight duct with the branch placed centrally on the plate

If B < 300: X = 50mm
If B > 300: X = 100mm
Calculations
L1 = See table
L2 = 1/2 - (L1 - (A/tg∞))
L3 = ((L1-L2)/cos∞)
- ((B/2) x tg∞)
Example
A = 700, B=350, C=700
L1 = 950mm
L2 = 0.5 - (950-(700/tg 29.6))
= 0.5 - (950-1332.22)
L2 = 382.72 ~ 383mm
L3 = ((950-383)/cos 29.6) - ((350/2) x
tg 29.6) = 652.10 - 99.41
L3 = 552.69 ~ 553mm
