Mesa MBF3820E Burglary & Fire Safe

Having a large interior in a safe is a nice benefit for all of your valuables, paperwork (passports, birth certificates, deeds, insurance information, wills, etc.), and even firearms. The Mesa MBF3820E Burglar & Fire Safe has interior dimensions of 36.50" high by 19.00" wide by 16.00" deep and offers 6.42 cubic feet of interior space. That is a lot of space! Plus, for organization purposes, it has two adjustable shelves. Additional shelves can be ordered if necessary for an additional cost.

Not only does the Mesa MBF3820E Burglar & Fire Safe offer a large interior space, but it is also burglar & fire rated as well. For all of your important valuables and documents, it offers a 2-hour fire rating, tested at outside temperatures up to 1830 degrees Fahrenheit. Mesa had this safe drop tested at the factory, which means it is built to survive a two-story fall. It also is classified based on the all-steel construction as a B-Rating for burglar protection. It is also drill and punch resistant.

An electric lock protects the outside of the Mesa MBF3820E Burglar & Fire Safe for quick access. You can also set your own combination that you can change at any time. An exterior key lock allows you to access your safe in an emergency if the digital lock fails. We also offer a higher-quality lock called the S&G Titan Digital Lock. Underwriters Laboratory has certified this lock.

Another great benefit is the interior outlet strip that includes three electrical sockets and 2 USB ports. The power source cord is included. You can plug in items such as light kits or dehumidifier rods plus electronic devices like a tablet, phone, or e-reader. With everything in one place, it's like it's your security hub!

Frequently Asked Questions

Is shipping really free?

Yes. Free delivery is included on every safe we sell, anywhere in the lower 48 states. The specific delivery method depends on the safe's weight: small package delivery for under 150 lbs, curbside, or garage delivery for heavier safes. See full shipping details →

How long will this take to arrive?

Shipping timelines vary by product. Check the availability status at the top of this page for the estimated ship date. Once shipped, transit time typically runs 5–10 business days, depending on your location. You'll receive tracking when the safe leaves the warehouse. Safes under 150 lbs ship via UPS or FedEx Ground, no appointment needed. Safes weighing 150 lbs or more ship via freight (LTL); the freight carrier will contact you directly to schedule a delivery appointment once the safe reaches your local terminal.

Can you deliver it inside my house and bolt it down?

We don't provide inside delivery directly, but we work with third-party installers across the country who do. Here's how it works: call us at 800-207-2259 for a recommendation in your area, and we'll provide the names and phone numbers of installers we've worked with. You contact the installer directly to arrange pricing for delivery and installation. Once you've agreed on a price, place your order with us using the installer's address as the shipping destination. The installer receives the safe, inspects it, and schedules your final delivery appointment. Some installers prefer to pick the safe up directly from the freight terminal. See inside delivery details →

Will this fit through my doorway?

Check the product's exterior dimensions (listed above) against your narrowest passage, interior doorways, stair landings, and tight turns. Most people remove the safe from the pallet before moving it indoors, so the safe's actual dimensions are what matter for doorways. Standard interior doorways (30–32" clear) accommodate most residential safes, but measure before ordering. Call us if you're uncertain. See where to locate your safe →


Can I change the combination myself?

Electronic locks: yes; it takes about 30 seconds. Instructions are included with your safe. Mechanical dial locks: no, changing a dial combination requires a licensed safe technician. Important: attempting to change a dial combination yourself (or having an unlicensed locksmith do it) voids the lock warranty. A licensed safe tech maintains the warranty. See lock operating instructions →


What if it arrives damaged?

Call us immediately — while you have 24 hours to report damage, calling right away gets the claim filed faster. Take photos of the damage and packaging before moving anything. For minor cosmetic damage, we typically send touch-up paint plus a partial refund. For significant damage, we send replacement parts or arrange a full replacement. Order Protection (optional at checkout) speeds refund payouts to 48–72 hours vs. 30–60 days through standard freight claims; replacement safes ship on the manufacturer's normal timeline regardless. See receiving your safe →

What's your return policy?

We offer a 30-day return policy on unused, in-original-condition products. The return freight for a heavy safe is substantial, so we strongly encourage you to call us before ordering if you're unsure about fit or configuration. See full return policy →

Can I place my order by phone?

Yes. Call us Monday–Friday, 8am–5pm Pacific at 800-207-2259. You have two options: we can take the full order by phone (we pause the call recording before you read your card number, so payment info is never stored), or we can build your order and email you a payable invoice link so you can enter your own payment details securely.
