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 on page 15; for example, part number 1020, found on catalog page 5, with a
standard Silver outer jacket is designated as part number 1020-01.
