Part Customization
This spec sheet details our standard offering.
3M has several capabilities that can provide a part tailored to
your specific needs. Ask your 3M sales representative or
customer service for more details.
Use of snap-in style latch/ejectors in either short (N3XXX
X5XX) or long (N3XXX-X6XX) styles, installed or shipped
separately (the -5 & -6 snap-in latches are dimensional and
functional equivalents to the -2 & -3 roll pin latches) which
are also available separately with roll pins included. Refer to
chart below.
If ordering snap-in or roll pin style latches separately, please use the below chart
