Meterguard's Key is easy to operate and remains coupled to the lock until released.

It is made of 100% stainless steel and is guaranteed not to rust. All parts subjected to

high stress are heat treated to maximize toughness. The key will remain functional

even when used in muddy water and will hold up to years of rigorous use. Meterguard

keys are almost impossible to duplicate and are only sold to registered utilities!
