Meterguard's new high thrust barrel lock and new adjustable end cap are a perfect combination for use on valves. Meterguard's barrel lock generates a unique clamping force of over 60 lbs and produces a tight, tamper proof installation when used on valves like this. The barrel lock's short tapered head is designed to deflect side blows, it will not break off, and it cannot be gripped with pliers. Meterguard's barrel lock is water tight; is made of thru-hardened stainless steel and is guaranteed not to rust.

This new end cap has an internal geometry that allows it to be infinitely adjusted and tightened against the valve's ears before locking the barrel lock in place. The taper on the end cap helps to prevent the use of prying tools and effectively deflects blows from blunt tools. The cap is made of thru-hardened stainless steel, it can sustain severe tampering without breaking or deforming, and is guaranteed not to rust.
