Installing replacement units in tower shelters is complicated. Once you remove the old unit and bring everyone onsite, you can only hope that the new unit will fit. Choosing a Bard unit relieves that worry. When you replace your equipment with same-size equivalent, the newest Bard units fit into the same location as the old – eliminating the need for adapters, re-cutting or shims. When you are faced with the need to upsize or downsize your equipment, Bard offers custom factory curb adaptors that ensure a fast and seamless transition.
