Polypropylene and wire seal for the applications that will not accept the traditional lead and wire seal. This seal will also comply with paragraph S.1.8. of Handbook 44. This seal is installed without any tools. A sealing press is not required. Simply insert the wire through the sealing holes and bend it around the insert and snap the seal closed. If the seal must be marked with identification numbers or letters, the seal would be stamped with special marking pliers prior to installing the seal. The wire is 14" long, single strand galvanized steel, 0.028" dia. Marking pliers have two special steel dies for impressing marks in one or both faces of the seal. The dies are custom embossed. Each die can have up to 4 letters or numbers i.e., initials on one die, company or year on other die. Allow 4 to 6 weeks for embossing dies.
