Fort Knox Guardian Vault Series
Personalized. Precise. Powerful.
The Fort Knox Guardian sets a new benchmark for advanced home and commercial security. With a 3/16” outer steel body, a 10-gauge inner liner, and a 5/8” reinforced fire door, the Guardian delivers layered, fortified protection that stands apart from every other safe in its class.
It comes fully equipped with high-end features usually reserved for top-tier vaults: 18 to 20 locking bolts, four star corner bolts, 90-minute fire protection at 1680°F, LED lighting, and a premium organizer system. If you want the strength of a Titan without the custom price tag, the Guardian is the one to beat.
What Makes the Guardian Exceptional?
- Double-Layer Steel Protection: 3/16" outer body and 10-gauge inner liner create an armored shell that resists forced entry, fire, and impact.
- 5/8” Reinforced Fire Door: Built with a 3/8” steel plate, two layers of C-rated fireboard, and 10-gauge reinforcement for total heat resistance.
- Star Corner Bolts: A Fort Knox exclusive—adds powerful anti-pry defense at every door corner.
- 18–20 Solid Locking Bolts: Strategically placed 1.5" bolts secure the sides, top, bottom, and corners of the door.
- 90-Minute Fire Rating at 1680°F: Six-sided fireboard insulation and Palusol™ dual thermal seal block heat, smoke, and flames.
- UL-Listed Burglary Protection: RSC-rated body and S&G Group II manipulation-resistant dial lock system.
