VHB Strip Identification
Very High Bond (VHB) Strip Identification
Printed on each Very High Bond (VHB) strip is an ID number (on the pull tab) and part number. Prior to installation, lay the strips out according to the
appropriate diagram.
Part numbers printed on the individual VHB strips (949-xxxx) are for visual identification only, and cannot be individually ordered.
VHB strips are only available as part of a starter or refill kit.
Verify that you have all the needed VHB strips.
Check the strips for damage. Make sure there are no wrinkles or exposed sections on the strip.
Damage can cause cosmetic gap issues and could make the display bond weak or create light leakage.
