3 Result (Pin-to-Pin – ABEFG)
4 Subtract D –
To find “D” pick number from chart below that is closest to,
but not greater than total from step 3.
Inches mm
3 X 84 = 252
4 X 84 = 336
5 x 84 = 420
6 x 84 = 504
3 x 2133.6 = 6400.8
4 x 2133.6 = 8534.4
5 x 2133.6 = 10668
6 x 2133.6 = 12801.6
Example–If result from Step 3 is:
500 inches “D” = 420 inches 12,000 mm “D” = 10668 mm
5 Result (C) Top Foil Length
