The AMSEC TF Series Gun Safes are a great product if you are looking for an affordable gun safe. Made with a 3/16" steel plate door and a 12 gauge body, the TF gun safe is sturdy and durable. It will offer you superior protection for your gun collection and other items that you cannot afford to lose. Another great feature is the Mercury Class I 30 minute fire rating, tested at outside temperatures of 1200 degrees F. To achieve this, AMSEC uses two layers of fire insulating material in between the layers of steel. This fire rating was designed so that interior temperatures never exceed 350 degrees F. There are many other great features on the TF series that make it the perfect, affordable gun safe that belongs in your home doing what it does best, protecting your guns and other valuable items.
