For commercial and multi-family development/construction:
Park Precast concrete vault with a fire sprinkler valve. The vault measures 9 feet x 5 feet, has 2 stainless steel access doors that open to 3' x 5', and has drop-in handles and utility key locks.
The unit (vault and valves) is in full compliance with the most recent fire and building codes and is ready for installation.
A new concrete vault and a new valve cost around $12,000, but we consider any reasonable offers.
