MiTek is committed to meeting every need you have
and we understand that stock connectors will not meet
all application or design requirements. Our Technical
Assistance Representatives will work with you to
develop and fabricate the Special or Custom connector
you need.
What is the difference between a “Special”
and a “Custom” connector?
A “Special” is a stock MiTek connector that is modied
within the limits listed in the Specialty Options chart for
that connector. A summary of Specialty Options can be
found on page 320 of this catalog.
A “Custom” is a connector that does not closely
resemble a stock or special part offered in our
catalog. Also, a “Custom” connector may be a stock
connector that is modied outside of the limits
listed in the Specialty Options charts or is not listed
in the catalog as having a specialty option available.
Product drawings must be provided by the customer
and will be manufactured by MiTek in accordance to
customer specications. Customs should be veried
prior to ordering and are not refundable.
See page 320-323 for additional information.
