• A tight fit is possible on a wide variety of valves or other installations. A tight fit discourages and reduces the effects of tampering by eliminating a gap or entry point for a pry bar etc.

  • Installation and inventory are greatly simplified because the same end cap fits every application.


  • Adjustable grip range of 3/8-3/4"

  • Stainless steel construction positively eliminates failure due to plating deficiencies and corrosion.

  • Through hardening, vs. case hardening, significantly increases the ability of the end cap to sustain severe tampering without breaking or deforming.

Meterguard's adjustable grip end cap is new to the lock industry. Now, one end cap can

be used to provide a tight fit on a wide variety of valves.  The unique internal geometry of

this new end cap allows it to be infinitely adjusted and tightened against the valve's ears

before securing the lock in place. A tight installation helps prevent the use of pry bars etc.

The cap is made of thru-hardened stainless steel and is guaranteed not to rust.
