Stealth CS25 Concrete Composite Burglary and Fire Safe

Looking for a safe that has similar fire and burglary protection to a TL-15 without the hefty price tag?

Introducing the all new, Stealth Concrete Composite Safes with advanced security features, a 90 minute fire rating and a gorgeous interior.

Starting with security, Stealth Concrete Composite Safes have a total door thickness of 4-1/2″ making it nearly impossible to pry open. Both the door and the body have a 2″ defense barrier of both an outer and inner steel plate with a concrete fill in the middle. Traditional home and office safes will have an outer steel shell with gypsum fireboard in the middle that is extremely easy to drill through. Concrete is incredibly difficult to drill through which is why it’s used on bank vaults and TL Rated Safes. With the Stealth Concrete Composite Safes you get similar security features found on TL Rated Safes without the massive price tag.

Keeping the massive door locked in place are 6 solid steel chrome-plated 1-1/4″ locking bolts, with three being active and three deadbolts on the hinge side. The door opens on two external heavy-duty steel strap hinges after the correct combination is entered into the UL Type 1 high security NL electronic lock. This lock is one of the most reliable locks in the industry and is backed by Stealth’s 2 year warranty. The lock is also protected by an outer steel escutcheon plate, internal hardplate and relocker that provides another barrier to a drill attack.

Stealth Concrete Composite Safes are rated for 90 minutes at 1200 degrees with the fire resistance provided by the concrete fill. Concrete is the best fire resistance material and if you take a look at all the safes that have passed the UL fire tests, all of them use concrete. Stealth also adds an intumescent door seal that expands to multiple times it’s size during a fire to prevent smoke from entering the safe keeping your contents safe and secure inside.

The Stealth Concrete Composite Safes are finished in a gorgeous off-white cream with a chrome drop down handle. What really differentiates this safe from the competition is the teal shelving and backplate that makes the interior really pop allowing you to easily see your contents inside. The finish makes this safe ideal for home, office or commercial use.

Stealth believes in and stands behind the concrete composite safe line by offering a 2 year parts and labor warranty on the lock and defects in materials and workmanship. If you want similar security and features of a TL Rated safe at less than half the price, you’ve just found your perfect safe, the Stealth Concrete Composite Safe.

    Damaged from shipping

    Safe appears to be very well built, think the bolts could be a little more solid. Safe arrived with a dent in it and a corner of the safe had a small crack in the metal which I am concerned about. Considering it is a fire rated safe also makes me question the durability of the safe knowing the metal became compromised from what appears to be minimal shipping damage.

    The price was great and the safe arrived in great shape along with accessories that were purchased. Quick turnaround on the order. Definitely will be doing business again with Armadillo.

    Bet good product

    You Get What you Pay for, So Very True

    This safe is spectacular....... After a long search and a great deal of research, I can't be happier with my decision. Your not going to be able to cut this monster is half with a circular saw, I actually watched a utube video of someone performing that on the first safe I purchased from Wal-Mart which I quickly return the same day it arrived ($149.00). The Continental is a beast. To say I would recommend this for any home owner is an understatement. I Thank you. Enjoy the Day.....

    Beautiful product and excellent service!

    Gorgeous watch box, built beautifully with amazing attention to detail and finishing. And a special shoutout to the support team for answering my questions and keeping me appraised on the details of the back order. Five star service!!
