Highfield Manufacturing Company products

Built on Highfield`s 80+ years of experience, our Garrison Lock and Key System offers the highest level of utility security and revenue protection. Improved features include preload capability, a dual-orientation key interface and a standard weather seal that eliminates sleeve rotation when fully enveloped in a lock housing. A new, classic-style key handle design also improves functionality. All non-interchangable, unique key code combinations are registered and controlled at the factory.

The REVPRO Barrel Lock and Key technology provides utilities one of the highest levels of security in the industry. Our proprietary design allows for thousands of non-interchangeable unique key code combinations that are registered and controlled at the factory. We believe our pin tumbler design is superior to a disk tumbler or conventional plunger design as it provides the highest degree of protection against pick resistance.

Highfield’s Armor Front Entry Meter Locking Rings are offered in hinged or solid styles, each with a different combination of materials and features. All rings can be provided with either a side-mounted seal tab or slotted seal ferrule that accepts wire and padlock seals. Each ring style has been engineered to ANSI standards with the user in mind, so installation is simple and straightforward. The machined lock housing accepts Highfield’s line of barrel locks as well as most barrel locks used today.

Highfield’s Snap Lock Rings are designed with AMI/AMR meter installations in mind. Cost-effective and user friendly, these Snap Lock Rings install in seconds without any keys, hand tools or barrel locks.

Cast Wing Valve Protector For ¾” Through 1¼” Valves With Seal Mount. Highfield’s Cast Wing Valve Protectors for gas and water utilities maximize protection for wing-style gas and water service valves. These lock-wing gas valve protectors are manufactured from a high-grade cast steel alloy, fully shrouded for maximum security and plated for protection against the elements.

Highfield’s Lock Seal Assemblies are cost-effective locking and sealing devices in a single unit. They can be installed on a wing or wingless style gas meter connection nut with mating security hardware. The lock seal provides positive protection against unauthorized use of gas as well as readily providing evidence of any tampering.

Highfield’s Shackle Lock and Seals secure a variety of gas and water utility pedestals and sheet metal enclosures without the use of a key or hand tools. Fabricated from case hardened steel, these reliable security devices replace disposable padlocks and seals. They can be supplied with printed, weather resistant utility warning tags.

Adjustable Minute Meter Guards are ruggedly engineered to secure all styles of ringless meter sockets and CT cabinets regardless of material thickness. For added strength and flexibility, our adjustable electric meter guards incorporate a hex design that allows the top plate to adjust in 60° increments. This feature is desirable when mounting near conduits or odd-shaped enclosures.
