Made of durable heavy-gauge steel, this fire-resistant security chest is engineered with double-insulated walls to protect contents from fire damage. It is fire tested at 750 degrees for 15 to 20 minutes. The size is big enough to house important file folders and large 9" x 12" documents. Ideal for small businesses and retail stores, a sturdy locking key latch keeps the box secure, and two handles make for easy upright carrying. SteelMaster Fire-Retardant Security Chest includes two keys for the single keylock.
