Meter Union Guards

Highfield’s Meter Swivel Nut Locks completely encompass the meter union nut to prevent gas meter tampering and bypassing.

Cost-effective and easy to install, each meter connector nut lock also comes with an optional blind disc used to stop the flow of gas for non-payment.

Our 20 LT Meter Union Guard has rugged three-piece construction made from case-hardened steel with corrosion resistant plating.

Additional benefits include:

Fully surrounds the meter union nut to prevent access
Blind disc supplied with each Meter Union Guard

To block the flow of gas, simply:

Turn off the gas valve
Remove the meter union nut
Insert the blind disc
Tighten the meter union nut
Install meter union nut lock & secure with barrel lock

Highfield also offers a meter union clamp, as well as gas meter fittings for security, including meter nuts, meter swivels, fire safety valves and more.
