High Security Barrel Locks for Utility Valves and Meters

End Cap

Barrel Lock

New high thrust barrel lock permits adjustment of the end cap before locking it in place.

New end cap adjusts tightly against the valve's wings to prevent tampering.

Meterguard's barrel lock provides superior revenue protection by integrating
security, toughness, durability, and reliability into a compact new design.


Meterguard's
unique barrel lock generates a clamping force of over 60 lbs and produces a tight, gap free installation when used on end caps, housings and rings. Our locks are made of thru-hardened stainless steel, are completely sealed to be  water tight, and are guaranteed not to rust!  Meterguard's barrel locks can easily handle dirt, mud, insects, foreign objects, water, ice, abuse and neglect for decades. The short tapered head cannot be gripped with tools and cannot be broken off.


Meterguard's barrel locks will fit/retrofit all industry standard barrel lock housings,
and are priced competitively with other brands of high security barrel locks.

A water utility in a major U.S. city cut its barrel lock expenditure
by more than 50% in the first year of use.     References available on request.
