Push these tags through hasps on cabinets, truck trailers, cargo containers, and other heavy duty equipment. A plastic coating provides corrosion resistance, but scratches easily. Cable or bolt cutters are required for removal. Tags are stamped with one letter and six random numbers. To install, snap apart the plastic attachment holding the bolt and lock together, then insert the bolt into the lock. Not offered blank for security reasons. Tags meet U.S. International Customs C-TPAT (Customs-Trade Partnership Against Terrorism) standards for high security seals.
