Protective Shroud / Recessed Installations

Flush Mount Installations

Meterguard's barrel lock is ideally suited for flush mount applications. The short tapered head cannot be gripped with pliers and will not break off. Meterguard's unique  lock generates a clamping force of over 60 lbs and produces a tight, tamper proof installation when used on meter boxes, housings, valves or rings.

Meterguard's new high thrust barrel lock and new adjustable end cap are a perfect combination for use on valves. The unique internal geometry allows the new end cap to be infinitely adjusted and tightened against a valve's ears before locking the lock in place.

Meterguard's lock cannot be gripped with pliers and will not break off. Protective recesses such as these are not a necessity but simply serve to amplify the exclusive advantages of Meterguard's barrel lock.
