Description

• National 8" Double Locking Security Seal is a  tamper proof, thermoplastic moulded device which has the advantage of a non-corrosive security seal and no sharp edges that may cut hands.
• ​In order to prevent duplication, consecutive serial numbering is closely monitored within our organization. 
• This is done by marking the plate seal with gold foil or black foil which can include customer’s name and / or logo
