Gun Safe Installation: From Delivery Day to Bolted, Level and Dry

Short answer: Gun safe installation, per the manuals: check the floor can carry the weight, get the safe in with a rated dolly and a helper, remove the shipping skid, set it against a wall, level it with shims so the door doesn't swing by itself, put a moisture barrier underneath, anchor it through the factory holes, then adjust the door and add power if you want a dehumidifier rod. Liberty Safe says its certified dealers will bolt a safe down for a fee. For big safes, that's the easy version.

This is the full setup checklist. The anchoring step has its own detailed guide: how to bolt a safe to the floor. Choosing the room is covered in where to put a gun safe. And if you haven't bought the safe yet, the gun safes page lists weights and dimensions so you can plan before delivery day.

Before installation: gun safe weight on the floor

Start with the floor, because it's the one part you can't fix after the safe arrives.

Liberty Safe's installation guide says to avoid placing heavy safes "on unsupported sections of a floor, especially on upper levels," that the safe "should be placed over multiple floor joists," and that "a professional should assess the floor's load-bearing capacity." Cannon's placement guide says concrete floors often provide strong support, while upper floors "may require evaluation by a professional." Liberty's use-and-care page suggests installing large safes, or safes in older homes, "near a load-bearing wall."

There's no universal floor rating in any manual we read, and there shouldn't be. Floors differ. The safe's weight is on its spec page; our guide on how much a gun safe weighs shows the range.

Then measure the route. Cannon and Liberty both say to measure doorways, hallways, stairs and turns. The SA Consumer Products Haven manual suggests walking the empty shipping box through to the final spot.

Delivery and unboxing: skids, pallets and a second person

Gun safes arrive bolted to something. Every manual we read treats removing it as a two-person job.

• SentrySafe calls pallet removal "a two-person operation," says the safe should stand upright on a flat, level surface, and says to close the door and lock the handle before tipping the safe off.
• SA Consumer Products (Haven) says to have a person stabilize the safe while the skid bolts come out, and to make sure the door is closed and locked first, because the heavy door "presents a safety hazard until the safe is bolted down or secured properly."
• Browning says some models ship with steel feet for transport that should be removed before final installation, and that shipping damage not noted on the delivery receipt must be reported to the carrier within 5 days.

Before the safe goes anywhere, the Liberty-made Cabela's manual says to test the combination, and to test it again once the safe is in its permanent location. A safe that won't open is easier to deal with in the driveway than in the closet.

The door is the heaviest moving part. It decides which way the safe falls.

Placement: against the wall, level, and off the bare concrete

Against a wall. The Haven manual says the safe should go next to a side wall with minimal space on either side, and flat against the wall and floor, removing baseboard or trim if necessary. Liberty's tipping guide favors a wall and, ideally, a corner.

Level, with shims. Liberty's use-and-care page: "ensure that the safe is level on the floor and use shims to level if needed. If the door automatically opens or closes, shim sides accordingly." The Haven manual says the same about a door that swings open too quickly or closes on itself.

A barrier underneath. Liberty recommends a moisture barrier between the safe and the floor to protect the bottom against rust, and mentions a carpet remnant. The Haven manual "highly" recommends a moisture or protective barrier on concrete and says exposing the safe to adverse conditions may void the warranty.

Gun safe on carpet: what the manuals say

A gun safe on carpet is common and workable, with two cautions from Browning's manual.

First, tipping: "Do not open the safe while located on an uneven or unstable floor or on plush carpet. The weight of the open door could cause the safe to tip forward." That warning sits in capital letters in the original, next to the anchoring instructions.

Second, rust: the safe bottom "will rust if exposed to a wet floor," and if carpet absorbs moisture, the bottom can rust from that. Browning's fix is a sheet of clear plastic between the safe and the carpet.

The anchor goes through the carpet and pad into the subfloor. Liberty's wood-floor kit covers carpet over a wood subfloor. (Carpet is soft. The joists are not. Aim for the joists.)

Anchoring: the step that makes the rest stick

Anchoring is where gun safe installation either finishes or doesn't. The short version from the manuals: four factory holes, mark through them, drill for your floor type, clean the holes, fasten through the safe floor. Browning lists a 3/8-in masonry bit for concrete and a 5/16-in wood bit for joist floors. Cannon's FAQ recommends 3/8 x 3-3/4 in concrete wedge anchors. Liberty warns that a post-tension slab should not be drilled.

The full walk-through — concrete, wood, tile, carpet, wall mounting and post-tension checks — is in our bolting guide.

If you'd rather not, Liberty's delivery page says its certified dealers bolt safes down "for a small fee" and suggests asking about it when you arrange delivery.

Door adjustment after installation

Once the safe is level and anchored, check the door.

Liberty's use-and-care page says the adjusted door "should fit snuggly but allow the handle to turn and engage the bolts without significant resistance." Browning's manual says to adjust its tension screws until the door closes without play between door and frame, and warns: "Do not over-adjust." Door adjustment hardware differs by brand, so this is a job for your manual's diagrams, not a general rule.

Power: outlet kits, knockouts and cords

A dehumidifier rod or interior light needs power inside the safe. How it gets there depends on the maker.

• Liberty Safe sells an electrical outlet kit with three 110V outlets and a six-foot exterior cord. Installing it means moving the safe away from the wall, and a bolted safe may need new anchor holes for the added depth. Liberty's Fatboy page lists the kit as adding 1/4 in to the depth, plus 1.5 in for a plug.
• Browning includes a power cord that attaches to the back of the safe and plugs into a standard outlet; a power strip is needed for several accessories.
• Cannon says most of its safes come with knockouts in the back, and warns: "When using the knockouts be careful not to make them any bigger."

Plan the power before you anchor. Moving an anchored safe a few inches for a cord is a second installation. For dehumidifier choices, see our gun safe humidity guide.

How to install a gun safe in your car

Vehicle safes are a different product with a different installation. The manufacturers keep it vehicle-specific.

Console safes. Console Vault says its safes are made to fit the factory console of specific vehicles, that "no cutting or drilling is required," and that installation means taking out the existing bolts, setting in the vault and replacing the bolts. It recommends checking the console type for your make, model and year before ordering.

Portable safes with mounts. Vaultek's support page describes two mounts for its Slider series. One wraps a strap around the seat and anchors with a security cable around "a fixed object or seat bracket." The other attaches a bracket using a seat-rail bolt from your vehicle. Vaultek adds: "we recommend consulting with a certified automotive technician before installation."

Seat bolts and rails are safety parts of the car. If the instructions involve removing one, follow them exactly or let a technician do it. Laws on carrying and storing firearms in vehicles differ by state; check your state's official guidance.

Here's the catch: the order matters more than the steps

Every step above is simple. The trouble comes from doing them in the wrong order. Anchor before leveling and the door swings by itself forever. Anchor before planning power and you're drilling new holes for an outlet kit. Open the door before anchoring on carpet and Browning's tipping warning stops being theoretical.

The manuals agree on the sequence: floor check, placement, level, barrier, anchor, door, power. Then the guns go in.

Skip it if: when you shouldn't install it yourself

• The safe is large or the route has stairs. Fort Knox and Liberty both point to dealer delivery and installation for big safes.
• The slab may be post-tensioned. Liberty won't drill one. Neither should you.
• It's going on an upper floor and nobody has checked the joists. Liberty says a professional should assess load-bearing capacity.
• It's a vehicle install that involves seat bolts. Vaultek's own advice is a certified automotive technician.

That's the installation, in order. Check the floor, level the safe, put a barrier underneath, plan the power, then anchor it through every factory hole. Test the combination one last time with the door open, and only then start loading.
