1 Pin-to-pin length
2 Subtract ABEFG –
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; 20,000 mm “D” = 19202 mm
5 Result (C) top foil length
After completing worksheet above fill in A, C, D, and G below. Add
“A” through “G” to confirm total equals your pin-to-pin measurement.
