Wall safes are an excellent choice for families with children, the elderly, and anyone who wants a safe that’s completely out of sight. In this guide, we share our Top 5 best fireproof wall safe picks along with some helpful tips and reviews of each safe. Before we get started with an overview of the safes, let’s go over a couple of key points to consider when choosing a fireproof wall safe for your home.

First, fireproof wall safes with the longest and most reliable fire ratings are always going to be thicker and require a deeper wall cavity. Compared to models without fire-resistant materials, the walls of a fireproof safe are thicker. In a standard 2×4 stud wall, a fireproof safe would end up having too little room inside it to make it worth building for the manufacturer. Be sure to keep this in mind before you buy because we’ve seen instances where people buy a safe only to realize later that it doesn’t fit inside their desired wall.

Second, there are different types of fireproof wall safes that feature true UL fire resistance ratings and others that have fire-resistant linings that do work well for short periods. In the chart below, you’ll find the fire ratings of each safe plus other important specs to consider for each model.

Third, each of the models in this guide can be installed as a hidden wall safe, though, not all of them sit completely flush with the wall. With a bit of planning, you’ll be able to hide any of these safes behind a picture frame, tapestry, or other wall decorations.

Best Fireproof Wall Safe Reviews

Our current favorite brands in this department are Amsec (American Security) and Gardall. These are two of the only brands manufacturing true fire-resistant wall safes with U.L. ratings. Other brands do hold up well to fire compared to standard wall safes, though, you may want to invest in a fireproof bag for your most important documents and valuables, which we’ll go over after the reviews.

Before the reviews, we want to point out that no safe is 100% fireproof because everything burns up given enough time. The key is to put the fire out before the end of the stated fireproof rating to avoid damaging items inside the safe. For this reason, “fireproof” is the same as “fire-resistant” or “fire-rated” when shopping for a fireproof safe.

#1) Amsec WFS149 Fireproof Wall Safe

The overall best fireproof wall safe on the market is the Amsec WFS149. Of the five safes in this guide, Amsec and Gardall models give you true UL tested and certified 1-hour fire protection. The fire protection ensures that the inside temperature of the safe does not go above 350º F for one full hour during fire exposure. To give you an idea of how good that is, paper begins to char at 450º F, so this safe keeps your important documents well below 450º for a full hour.

Outside of fire protection, this is a beautiful safe with a black granite finish and an ample level of security with two 1/2″ steel locking bolts. It features two entry methods with a combination lock and key access. Typically, we’re not huge fans of key access since it’s prone to pick attacks, but considering this is a hidden wall safe, it’s not a bad idea to know you’ll always be able to access the safe.

Inside the safe, there’s a nice little drawer shelf and one main shelf. Plus, there’s enough room in this safe to use it as a fireproof gun safe with its near 10″ of interior depth. You’ll have no problem storing jewelry, documents, electronics, and other valuables while still having enough room for a desiccant to prevent moisture buildup inside the safe. All in all, this is an excellent safe, and the fact that it costs about the same as the Protex safe at the time of this writing makes it the better buy.


  • Actual U.L. certified fire protection
  • The best wall safe for the money of the five in this guide
  • Two entry methods ensure you don’t lock yourself out
  • No need to worry about battery power
  • Spacious interior, especially for a fireproof model
  • Secure, thick 1/2″ door
  • U.L. listed Group II Combination lock
  • Easier to install than the Gardall safe
  • Smooth-rolling dial
  • The recessed door and low-profile dial keeps the safe flush with your wall


  • Too deep for standard walls
  • Be sure to consider it weighs 104 lbs before ordering in case you need to hire someone to lift/install it

#2) Protex WES2113-DF Fire Rated Wall Safe

If you’re having trouble finding a spot inside your home to install an Amsec safe, this safe by Protex is shallower at 8″ deep compared to the 15 3/8″ depth of the Amsec WFS149. The most important point to consider when choosing between this model and the model above is the fire rating. This model by Protex is lined with fire-resistant materials to protect the contents of the safe against fire damage for up to 30 minutes.

Compared to the Amsec and Gardall models in this guide, this safe and the Mamba Vault provide less fire protection. The advantages of this model compared to Gardall and Amsec are its smaller depth to make it more universal, and its lighter weight makes it easier for most folks to install. Additionally, you might prefer keypad access rather than a combination lock for quicker access.

Another reason we like this safe is it features two override methods in case the keypad fails. You’ll find a key override system and a power override to ensure you don’t get locked out. As far as security, this model provides a decent level of security with two locking bolts along with a 3/16″ steel door & flange. In total, it has .75 cubic feet of storage space and two removable shelves to arrange the interior to your liking.


  • Keypad entry for quicker access than a dial lock
  • Fairly heavy 3/16″ solid steel door
  • Key lock override system to prevent getting locked out
  • Two locking bolts for good pry attack resistance
  • Soft velvet fire-resistant lining to avoid damaging or scratching your jewelry, handguns or other valuables
  • Made to install between 16″ on center studs
  • Removable shelves for customizable organization
  • Includes mounting hardware


  • Not as fire-resistant as Gardall or Amsec models
  • Not tested or certified to U.L. standards
  • Amsec and Gardall models are heavier duty

#3) Gardall WMS912-G-K Fireproof Wall Safe (w/ Flange)

Gardall WMS912-G-K Fireproof Wall Safe (with flange)

Now for one of the most secure safes of the five in our guide made by one of our favorite safe manufacturers. Make no mistake, this is a heavy-duty steel safe that no one is ripping out of your wall or running off with too easily. Unlike the Mamba Vault and Proteck safes, this model surpasses the 100-lb mark for enhanced security. In addition to its heavy-duty design, this safe – like Amsec models – is UL certified. You’ll find a U.L. 350° one-hour fire label on the safe to verify that.

Additionally, the WMS912-G-K sports a recessed door and low-profile combination dial, making it a great concealed wall safe for a wide variety of items, especially since it has a bit more interior depth than the Amsec WFS149. In addition to the combination lock, you also have the option to open the safe using the included keys.

The inside of the safe features a pull-out tray for storing smaller valuables, however, there are no interior shelves. One drawback is the more sophisticated installation process using the included 2″ flange. Unlike the other four safes, this safe bolts to the flange only rather than fastening it directly to the wall studs, which is definitely something to consider before making your final decision.


  • Authentic U.L. 1-hour fire rating with label
  • Heavier and more secure than the Proteck and Mamba Vault models
  • No need to rely on battery power
  • Multiple entry methods
  • Gardall has been around since 1950
  • Four sizes available
  • A convenient pull-out tray
  • Gardall warranty


  • The most complicated installation of the models in this guide
  • Does not fit standard stud walls
  • No interior shelves

#4) Amsec WFS149E5 Fire Resistant Wall Safe

You’ve probably already noticed that this safe is very similar to Amsec WFS149, and that’s because both safes are about the same. The main difference between the WFS149E5 and WFS149 is the access methods. With the WFS149, you have the option to access the safe via the combination lock or by using the override key.

With WFS149E5 or WFS149E5LP models, there’s no override key, and this is very important to consider should you choose this model. Safes without override key access come with their own pros and cons. The clear advantage is that no one can pick the key lock, and safe key locks are usually easy to pick with tools commonly found on the internet. The clear disadvantage is that if the keypad lock fails, then you’re locked out of the safe.

The good news is the WFS149E5 houses the 9-volt keypad battery on the outside of the safe, so there’s no worrying about getting locked out due to no power. The only concern is whether the keypad lock fails, and it’s undoubtedly worthy of consideration, though, we don’t think of it as a dealbreaker because we’re fans of safes without key access.


  • U.L. 1-hour fire rating
  • No chance of thieves or anyone picking the lock with no key access (we really like this feature for gun owners with children)
  • 9-volt battery housed on the outside
  • U.L. listed E-Lock with illuminated keypad
  • Factory reset combination option in case you lose or forget your combination
  • 15-minute penalty lockout after four failed entry attempts
  • Optional silent mode for stealth access (another good feature for gun owners)


  • Though very slim, there’s the chance of being locked out if the keypad fails
  • Too deep for standard walls, however, it’s made to fit between wall studs

#5) Mamba Vault Fire Resistant Wall Safe

Did you notice that the Mamba Vault is basically the same safe as the Proteck vault? There are several versions of this safe available from different manufacturers, and we like the Proteck and Mamba Vault models the most. If you plan to go with this model, it’s a good idea to compare the prices between this one and the Proteck safe to get the best deal.

The same as the Proteck model, the Mamba Vault is not officially U.L. certified. Rather, it features a fireboard lining along with a soft velvet interior to protect your valuables against fire and scratching. Also, it has the same 30-minute fire rating as the Proteck model, just keep in mind that this is not an official UL fire rating.

Outside of that, as we mentioned already, this is essentially the same safe as the Proteck model. It comes down to your preference and the price of each safe at the time you’re ready to buy to make your final decision easier.


  • Two entry methods with key access to ensure you never get locked out
  • Decent 30-minute fire resistance
  • The electronic keypad sits almost flush with the door making this a great hidden wall safe
  • Plush velvet interior lining
  • Very easy to use and program
  • Easier to install than Gardall or Amsec models


  • Less safe for the money compared to going with Gardall or Amsec
  • You may want to double up with fireproof document bags

Final Tips

These five models are currently the best fireproof wall safes on the market. As a reminder, always consider the depth of the safe you plan to buy before making your final decision since all five safes are deeper than standard wall safes. If you’re not handy, it’s wise to contact a contractor before purchasing a wall safe to get a clear idea of your installation options and an estimate.

Finally, if you want a truly fire-resistant wall safe, stick with the Amsec and Gardall models with 1-hour fire ratings. While the Proteck and Mamba Vault safes do provide some fire resistance, it’s not as reliable as what Amsec and Gardall offer.

For an additional layer of security, we like to store our most valuable documents and possessions inside a fireproof document or money bag inside the safe. Below is an example of a good legal size fireproof document bag:
