The first flat-packed, self-assembly guard for the protection of outdoor VRF / VRV units. These protective AC guards protect the unit against vandalism and accidental damage. The base pack suits single VRF / VRV units; any number of extender packs can then be added to the base pack for multiple-unit installations. All sliding panels can be easily removed to maintain the unit. Protective AC Cages are made of weather-resistant galvanized steel.
