Tracker Safe's are built with one very important mission: to protect what matters most to our customers. As our world is a dangerous place, there is not a better or more reliable safe than a Tracker Safe to store the valuables that you cherish. The E Series is our economy line of fire rated safes with 14-Gauge steel, 1 layer of fireboard, 30 minute fire rating and 1 in. diameter bolts, and a lever handle. Great for the first time gun buyer or someone needing additional ammo storage with a good safe without breaking the bank.
