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
7 x 84 = 588
8 x 84 = 672
9 x 84 = 756
10 x 84 = 840
11 x 84 = 924
7 x 2133.6 = 14935.2
8 x 2133.6 = 17068.8
9 x 2133.6 = 19202.4
10 x 2133.6 = 21336
11 x 2133.6 = 23470
Example–If result from Step 3 is:
800 inches “D” = 756 inches 20,000mm “D” = 19,202mm
