Guide to Stack-On Gun Safes

If you’re looking for a Stack-On gun safe, you probably are seeking a safe that offers a perfect mix of ease of access and security. Stack-On gun safes are built with an outdoorsman in mind, making their safes durable, secured and functional.

The Stack-On Brand

Stack-On has been in the gun storage and safety market for more than four decades, and with a long product line of high-quality items, the company has a large customer base. This brand doesn’t have a reputation like its leading competitors in the industry, but it is trusted by many pros because they use high-quality steel to manufacture their safes.

Founded in 1972 by John Lynn, the Stack-On Product Company offers gun safes, gun cabinets, garage storage, organizers and tool boxes. They are headquartered in Chicago, Illinois and have their own manufacturing and fulfillment facilities in several locations. The company is most known for its gun safes, which are all made for both handguns and long guns. 

Best Features of Stack-On Gun Safes

Why should you choose or consider Stack-On safes? Here are some of the great features that they offer with their safes.

1. Price

No other gun safe can beat Stack-On when it comes to other brands. It’s durable, has multi-lock mechanisms and good resistance qualities that cost less than other brands. The price difference is always considerable.

2. Warranty

Stack-On gun safes offer limited lifetime warranty, under which the manufacturer promises to replace or repair their product if it’s damaged due to fire, water or theft. They generally provide a five-year warranty for manufacturing defects. In case any flaw or damages can be handled by a Stack-On local workman, the company can pay for the freight for the product to be shipped to their facility. 

3. Fire resistance

The company offers fire safety on most of its secure storage product lines, but not on its SS series. Most of the Stack-On gun safes are ETL-rated and have been built to withstand temperatures of up to 1400 degrees Fahrenheit for 30 minutes. It’s not that impressive, so if you live far from the nearest fire station, it’s advisable to look for something else.

However, it’s commendable that the company is explicit about the nature of their safe’s fire safety. They mention that it’s adequate to protect your guns from fire hazards for a certain time period, and they say that it’s not suitable for storing electronic or optical data because the inside of the safe can reach temperatures around 350 degrees even with fire safety in effect.

4. Water resistance

There are not many waterproof safes on the market, but this is where Stack-On gun safes excel. If your area is prone to flooding and you keep your firearms in the garage, you will need a safe that can handle partial water submersion. You can opt for anything from the Sovereign series and the Total Defense series, which offers gun safes that are waterproof for up to 2 feet of water for 72 hours straight. 

5. Security

Security is the most important factor you should be looking for in a gun safe, and the Stack-On safes provide a level of security you can rely on. Their safes come with 2-way or 4-way locking systems with live action bolts ranging from 1” to 1.5” in length. These bolts help resist prying, and their safes can withstand drilling and theft because of its anchor points. 

Most gun safes from Stack-On classify as a California Department of Justice-approved firearm safety device. Bear in mind that it’s not the same thing as UL penetration rating found in higher-end products from other manufacturers, but considering the price, it’s acceptable.

6. Locking options

You can find electronic and combination locking options for most of the manufacturer’s offerings. The electronic locks are backlit and battery operated, and it can support 3 to 8-digit programmable codes. They offer a back-up key in case the electronic functionality fails.

7. Storage features

All gun safes from Stack-On have fully-carpeted interiors. Most models also have one or more removable shelves so you can customize storage.
