Header Ordering
Information
The “Base Part Numbers”
Chart at right shows the base
part number.
Prefixes and suffixes are deter-
mined by the number of post
positions in the header. For
example, the complete part
number for a 10-position
header with straight posts and
with pegs would be:
Base number 644486 plus
prefix-and-suffix
4- — -0
The correct ordering number is
4-644486-0
See page 15 for an explanation of
