Safe-T-Cover’s patented MUNI-LOK is a security locking system that uses the traditional underground vault hatch mechanism to securely lock above-ground enclosure doors.
Now municipalities and contractors can specify a single locking mechanism for their existing vaults and above-ground enclosures using the same key.
Above-ground backflow preventer assemblies, backflow devices, pumps, valves and other components are often left exposed and unprotected, especially if installed in cages. When enclosure doors are not secured, rain, debris, animal infestation and vandalism can affect backflow equipment.
MUNI-LOK Benefits
Marine-grade aluminum enclosures equipped with MUNI-LOK are the optimal backflow enclosure choice in any region or climate. They offer corrosion resistance, freeze protection and easy access for maintenance. This combination meets ASSE 1060, the industry standard for backflow device enclosures. Available for standard enclosures and custom sizes.
