Each Ultra-Vanshield® shielding gasket profile shown in
the preceeding product section is available with a wide selection
of conductive outer jacket choices. To construct a discrete
part number for your application, add one of the suffixes shown
below after the part number, as described under ordering; for
example, part number 1020, found in the product section, with
a standard Silver outer jacket is designated as part number
1020-01.
