Will you be the one who feels the heat when your business records go unprotected for one day too long? Don't let that happen! Our File Room or Vault Doors can save your business. To ensure protection of records and other valuables, our file room doors come in two models and bear a UL Class 350-1 Hr. Fire Resistance rating. Meanwhile, our vault doors, with six models available, have UL Class ratings of 350-2 Hr., 350-4 Hr. and 350-6 Hr. Each door is locked with five bolts on either side, which are heavily nickel plated and permanently lubricated. This boltwork automatically retracts when the handle is opened and automatically extends when the door shuts. In addition, the bolts are checked by a three-tumbler Group II Key Change Combination Lock that is equipped with a UL certified Re-locking Device. This device resets the lock bolt if the lock is damaged by tool attack. A second UL certified device automatically deadlocks the door in case of tool or torch attack. All hinges have roller-thrust bearings and can be placed on either side of the door with stainless steel covers available, some at an additional cost. Each door is also fitted with an easily operable escape mechanism inside and a beveled vault entrance for easy passage of wheeled carts. The doors come finished with textured vinyl paint in colors of gray, charcoal, forest green and tan, though you may consult the factory about customized colors.
