How To Use metal Seals

Align the Seal: Insert the strap or locking mechanism of the seal through the designated hole or slot in the item you are securing.

Lock the Seal: Push the seal strap into the locking mechanism until you hear or feel it click securely into place. For ball seals, ensure the strap locks into the double-ring mechanism.

Check the Seal: Gently pull on the seal to confirm it is securely locked. Verify that the unique serial number or embossing is clearly visible for easy identification.
