Material
0.9mm galvanised steel
Sizes
Common sizes are a stock item
Special requirements are manufactured to order
Dimensions
Refer to table - customer to specify A, B, & C

Please note the Branch 'B' determines L1, as in the table below

The maximum diameter reduction between A & C is 200mm. B must however, not be larger than or equal to (A+C)/2

In the case of double branch pieces, the largest branch determines Length L1
Calculations
L1 = See table
L2 = (L1/2) - ((A+C) / (4 tg∞))
L3 = ((L1-L2) / cos∞°))
- ((B/2) x tg∞°)
Example

A=650, B=500, C=450
L1 = 1250mm
L2 = (1250/2) - ((650+450)
/(4 x tg 29.7)) = 625 - 482.13
L2 = 182.87 ~ 183mm
L3 = ((1250-183)/cos 29.7) - ((500/2) x
tg 29.7) = 1228.37 - 142.60
L3 = 1085.77 ~ 1086mm
