Quadra-Seal® security seals make it virtually impossible to compromise
the security for which they are designed to protect.

Quadra-Seals® are the first and only security seals that are unitarily molded to offer tamper-evident
security that is equal to or superior to any comparable plastic seal.

Once sealed, four design characteristics eliminate any chance of someone pushing, pulling, picking,
heating, or in any way compromising the security.

Every numbered seal of each color and length is uniquely serialized. Pull-Tight Quadra-Seals®
can be imprinted with a custom identification.
