The UNI110 Twister Seal is an easily applied meter security seal for all types of meters, including gas, electricity and water meters. The clear polycarbonate body houses a coloured insert with a one-way rotating locking mechanism. Once sealed, the locking mechanism is completely encased, meaning tampering is extremely difficult - any tamper attempts are clear from viewing the locking insert through the transparent body. The seal is appropriate for installers on the Ofgem Approved Meter Installers (OAMI) list - your customised OAMI number and sequential security numbers are laser-engraved onto flag of the seal.

Available with optional larger flag for increased marking area (110XL and 110WF), and can be printed with a white patch for increased barcode contrast on transparent body.

• Transparent body encases sealing mechanism for excellent tamper-evidence
• Suitable for sealing of gas meters by certified OAMI installers
