What Cannon safes are and how they fit into the safe market
Cannon is a manufacturer of home and office safes based in the United States, owned by Lerner Stores Corporation. They make fire-rated safes, burglary-resistant safes, and combination models for storing documents, cash, firearms, and valuables. Cannon safes range from small personal safes under $200 to large floor models over $1,000, and they are sold through retailers like Tractor Supply, Walmart, and specialty safe dealers rather than directly to consumers.
Cannon competes in the mid-range safe market alongside brands like SentrySafe, Stack-On, and Gardall. They do not manufacture the highest-end luxury safes (those come from brands like Browning or Liberty), nor do they make the cheapest portable models. Their positioning means you will find Cannon safes in homes and small businesses where the owner wants fire protection or theft resistance without paying premium prices.
Understanding what Cannon offers requires comparing them directly to what other manufacturers offer at similar price points, because the safe you choose depends on what you are protecting, how much you can spend, and how much protection you actually need.
Key Takeaways
- Cannon safes are mid-range American-made safes that emphasize fire protection and are sold through major retailers, not directly by the manufacturer.
- Fire ratings on Cannon safes vary by model — some protect contents for 30 minutes at 1,200 degrees, while others offer no fire rating at all — so you must check the specific model's rating before buying.
- Cannon safes use mechanical combination locks, electronic keypad locks, or biometric locks depending on the model and price, and each type has different failure modes and maintenance needs.
- Burglary resistance in Cannon safes comes from steel thickness and bolt design, but most home safes (including Cannon) are not rated for burglary protection by independent testing bodies.
- Comparing Cannon to SentrySafe, Stack-On, and Gardall requires looking at the specific model's fire rating, lock type, interior space, and warranty rather than assuming all safes from one brand are the same.
Fire protection ratings and what they mean for your documents
Cannon's main selling point is fire protection. Most Cannon safes carry a fire rating, which means the manufacturer tested the safe in a furnace and measured how hot the interior got. A common Cannon rating is "30 minutes at 1,200 degrees Fahrenheit" — this means the contents stayed below a certain temperature (usually around 350 degrees inside) for 30 minutes while the outside burned at 1,200 degrees.
Not all Cannon models have the same fire rating. A small Cannon personal safe might offer 30 minutes of protection, while a larger model might offer 60 minutes or 90 minutes. Some Cannon models have no fire rating at all — they are burglary-resistant only. You must look at the specific model's specifications, usually found on a label inside the door or in the product manual, to know what you are getting.
Fire ratings matter if you store documents, photos, or cash that cannot be replaced. They matter less if you are storing items you have copies of elsewhere or items that can survive heat (like some firearms and jewelry). SentrySafe and Gardall also offer fire-rated safes at similar price points, so fire protection alone does not distinguish Cannon from competitors — you are comparing the specific rating (30 minutes versus 60 minutes) and the price for that rating.
Lock types: mechanical, electronic, and biometric
Cannon safes come with three main lock types. Mechanical combination locks require you to dial a combination by hand — no batteries, no electronics, and they work even if the safe is damaged in a fire. The downside is that dialing takes time and you cannot change the combination without calling a locksmith. Electronic keypad locks let you enter a code on a button pad and open the safe in seconds. They run on batteries and can be reprogrammed with new codes, but if the batteries die or the electronics fail, you may need a locksmith to open it.
Biometric locks scan your fingerprint and open the safe if the print matches. Cannon offers biometric models at higher price points. Biometric locks are fast and do not require remembering a code, but they can fail if your fingers are wet, dirty, or scarred, and they require battery power like electronic locks.
Each lock type has a different cost and a different failure mode. Mechanical locks are cheapest and most reliable over decades, but slowest to use. Electronic locks are faster and more flexible, but depend on batteries and electronics that may fail. Biometric locks are fastest but most dependent on technology and environmental conditions. Your choice depends on how often you open the safe and how much you value speed versus long-term reliability.
Steel thickness and bolt design in Cannon safes
Burglary resistance in a safe comes from how thick the steel is and how many bolts hold the door shut. Cannon safes typically use steel walls ranging from 0.5 inches to 1.5 inches thick, depending on the model and price. Thicker steel resists prying and drilling longer, but also makes the safe heavier and more expensive.
Bolts are steel rods that extend from the door frame into the safe body when locked. More bolts and longer bolts make the door harder to force open. A small Cannon personal safe might have 4 bolts, while a large floor model might have 8 or more. The bolt material and design matter as much as the count — hardened steel bolts resist drilling better than soft steel.
Most home safes, including Cannon, are not tested or rated for burglary resistance by independent bodies like Underwriters Laboratories (UL). This means you cannot compare a Cannon safe's burglary rating to a SentrySafe or Gardall safe using a standard number. Instead, you compare the specifications — steel thickness, bolt count, bolt material — and understand that no home safe will stop a determined thief with power tools for more than a few minutes. Home safes are meant to deter casual theft and keep honest people honest, not to withstand a professional burglary.
Interior space and what fits inside
Cannon safes come in many sizes, from 0.5 cubic feet (small enough for a desk drawer) to 12 cubic feet (large enough for a filing cabinet). The interior space determines what you can store. A 2 cubic foot safe holds documents and a few small items. A 5 cubic foot safe holds documents, cash, jewelry, and a handgun or two. A 10 cubic foot safe holds multiple firearms, documents, and larger valuables.
The interior layout also matters. Some Cannon safes have a single open chamber. Others have shelves, drawers, or door pockets that let you organize items and use the space more efficiently. If you plan to store firearms, check whether the safe has a gun rack or whether you will be stacking guns on the floor. If you store documents, shelves make it easier to find what you need.
Cannon publishes the interior dimensions of each model, usually in cubic feet and also in inches (height × width × depth). Before buying, measure the items you plan to store and compare them to the safe's interior dimensions. A safe that looks big enough on the shelf may be too small once you account for the thickness of the walls and the space taken up by the lock mechanism.
Warranty and what it covers
Cannon safes typically come with a limited lifetime warranty on the safe body and a shorter warranty on the lock mechanism (often 1 to 5 years, depending on the lock type). The lifetime warranty on the body usually covers defects in materials and workmanship, but not damage from fire, flood, misuse, or normal wear.
The lock warranty is shorter because locks fail more often than the safe body. An electronic lock might fail after 5 years of use, and the warranty covers replacement of the lock, not the entire safe. A mechanical lock usually lasts decades and may be covered for the life of the safe.
Warranty coverage varies by retailer and by the specific model, so check the warranty document before buying. Some retailers offer extended warranties for an additional cost. The warranty does not cover the cost of a locksmith if you forget your combination or the lock fails — it covers replacement of the defective part only.
Comparing Cannon to SentrySafe, Stack-On, and Gardall
SentrySafe is the largest home safe manufacturer in the United States and offers a wider range of models than Cannon, from small portable safes to large floor models. SentrySafe safes are often cheaper than Cannon at the same size, but many SentrySafe models prioritize fire protection over burglary resistance. Gardall is a smaller American manufacturer that emphasizes burglary resistance and is often more expensive than Cannon. Stack-On is a budget brand that offers basic safes with minimal fire or burglary protection at low prices.
The comparison depends on what you need. If fire protection is your priority, compare the fire ratings and prices of Cannon, SentrySafe, and Gardall models at the same size — you may find SentrySafe cheaper or Gardall offering more burglary resistance for a higher price. If you want both fire and burglary protection, Gardall models often cost more than Cannon but offer thicker steel and more bolts. If you have a tight budget, Stack-On offers basic safes at lower prices, but with minimal protection.
The best comparison is model-to-model, not brand-to-brand. A specific Cannon 5 cubic foot fire-rated safe should be compared to a specific SentrySafe 5 cubic foot fire-rated safe by looking at fire rating, lock type, steel thickness, bolt count, interior layout, warranty, and price. That comparison tells you whether the Cannon is worth the price difference or whether another brand offers better value for your needs.
Where to buy Cannon safes and what to check before purchasing
Cannon safes are sold through Tractor Supply, Walmart, Amazon, and specialty safe retailers. Prices vary by retailer and by whether the safe is on sale. Tractor Supply often has sales on Cannon safes during holiday weekends. Walmart carries a limited selection of smaller models. Specialty safe retailers may have more models in stock and can answer questions about specific features.
Before buying, check the product label or manual for the fire rating, lock type, interior dimensions, and warranty. Read customer reviews on the retailer's website, but remember that reviews often come from people who had a problem — satisfied customers are less likely to write reviews. Look for reviews that mention how long the safe has been in use and whether the lock still works reliably.
Consider delivery and installation. Safes are heavy — a 5 cubic foot safe weighs 300 to 500 pounds — and most retailers offer delivery for an additional fee. Some retailers will place the safe in your home, but not bolt it down. Bolting a safe to the floor or wall requires a drill and concrete anchors, and you may want to hire someone to do this. Factor delivery and installation costs into your total purchase price.
Frequently Asked Questions
Do Cannon safes protect against fire better than SentrySafe?
Not necessarily. Both brands offer fire-rated safes with similar ratings — 30 minutes at 1,200 degrees is common for both. The specific model matters more than the brand. Compare the fire rating printed on the label of the exact Cannon model you are considering to the exact SentrySafe model, and you will see whether one offers more protection.
Can I change the combination on a Cannon safe with a mechanical lock?
No. Mechanical combination locks cannot be reprogrammed without opening the safe and changing the internal mechanism. If you want to change the combination, you must call a locksmith, which costs $50 to $150. Electronic and biometric locks can be reprogrammed by you using the manufacturer's instructions.
What happens if the batteries die in my Cannon safe with an electronic lock?
Most Cannon electronic locks have a backup battery compartment inside the safe door, and you can replace the batteries without opening the safe. Some models also have a mechanical override key. Check your specific model's manual to see what backup options are available.
How much weight can the floor support if I put a large Cannon safe in my home?
A 10 cubic foot Cannon safe weighs 500 to 700 pounds. Most residential floors can support this weight if the safe is placed over a floor joist or beam. If you are unsure, consult a structural engineer or contractor before placing a large safe. Placing a heavy safe on a weak floor can cause it to sink or damage the floor.
Is a Cannon safe waterproof?
Cannon safes are fire-rated but not waterproof. If your safe is in a basement or an area prone to flooding, water can seep in around the door seal and damage contents. If you need waterproof storage, look for safes specifically rated for water protection, or store important documents in a waterproof container inside the safe.
