þþ *Note: The stored on-center spacing is used as the maximum allow-

able spacing. Therefore, it is assigned to the side with the largest en-

tered pitch. In this example, the “irregular” side pitch is larger than

the “regular” side pitch; thus, the irregular side is calculated using the

maximum on-center value (16 inches). If the regular pitch side had

the larger pitch, it would require the larger (16 inches) on-center.
