The Hidden Door Store team fully assembles and tests each door before shipment. This includes installing the door in our testing jig that simulates the required wall conditions.

The door is crated and shipped assembled so installation is fast and easy for a handy homeowner or contractor.

Unlimited phone support – though rarely needed – is both available and free.

How to Install a Vault Mirror Door

Step 1: Gather Your Installation Tools

Before you begin, you’ll need:

• Laser level
• Drill
• Impact driver
• #2 Phillips bit
• #3 Phillips bit
• T25 Torx bit
• T30 Torx bit
• Wood or composite shims
• Two 2×4 blocks (approximately 12 inches long)
• Tape measure

Step 2: Inspect the Vault Mirror Door

Before moving any components:

• Open the shipping crate carefully.
• Inspect the frame, steel door panel, and mirror face frame for shipping damage.
• Leave the protective shrink wrap on until installation begins.
• Save all packaging until installation is complete.

If anything appears damaged, stop installation and contact Hidden Door Store before continuing.

Step 3: Prepare the Wall Opening

Vault mirror doors require a highly accurate rough opening.

Before installation, verify:

• Opening dimensions match the product specifications.
• Width and height vary by no more than ¼ inch.
• The opening is square.
• The threshold sits at least 4 inches above the baseboard to create the appearance of a wall-mounted mirror.
• Because of the door’s weight, double studs are recommended on both sides of the opening, especially for ballistic models.

Step 4: Verify the Wall Is Level, Plumb, and Flat

Using a laser level, check:

• Floor is level.
• Both sides of the opening are plumb.
• Corners are square.
• Wall surface is flat from front to back.

Hidden vault doors cannot compensate for warped or uneven walls, so any framing issues should be corrected before installation.

Step 5: Install the Required Power Outlet

Vault Mirror Doors require electrical power.

Before installation:

• Install a standard 110V outlet inside the hidden room.
• Position the outlet within 15 feet of the doorway.

This powers the electronic locking system and access controls.

Step 6: Move the Door Components

Unlike other hidden doors, the Vault Mirror Door ships in three separate pieces:

• Steel door frame
• Steel door panel
• Decorative mirror face frame

To safely move them:

• Plan your route beforehand.
• Use at least four people.
• Keep each component wrapped until positioned near the opening.
• Place each component on a blanket to protect the finish.

Step 7: Install the Steel Door Frame

Position the steel frame inside the rough opening.

Then:

1. Slide the frame into place.
2. Shim the hinge side until perfectly plumb.
3. Secure using the supplied lag screws.
4. Shim and secure the latch side.
5. Verify the frame remains square before tightening all hardware.

A properly aligned frame is critical for both concealment and security.

Step 8: Install the Steel Door Panel

With the frame secured:

1. Assemble the temporary support platform.
2. Lift the steel door panel onto the platform.
3. Align the hinges with the frame.
4. Secure each hinge using the supplied machine screws.
5. Remove the support platform.
6. Recheck that the frame is still level and plumb after the door’s weight has been added.

Because of the door’s weight, this step requires multiple people.

Step 9: Attach the Mirror Face Frame

With the steel door installed:

• Position the decorative mirror frame.
• Slide it onto the pre-installed mounting pins.
• Confirm it is fully seated.
• Connect the fingerprint scanner, if your model includes one.

The mirror frame completes the concealed appearance of the vault door.

Step 10: Connect Power

Connect the electronic locking system by:

• Installing the power transfer cable.
• Mounting the transfer housing.
• Connecting the control box to the nearby 110V outlet.

Keep the door open throughout this process.

Step 11: Test the Locking System

Before closing the door:

• Test the manual emergency release.
• Test the interior egress button.
• Verify the electronic latch functions correctly.
• Test the RFID reader.
• Test the keypad (if equipped).
• Test the fingerprint scanner (if equipped).

If any component does not operate correctly, stop installation before proceeding.

Step 12: Perform a Full Function Test

After the initial tests:

• Close the door.
• Verify it unlocks using the interior release.
• Test RFID cards.
• Test the keypad.
• Test the fingerprint scanner.
• Confirm all locking rails engage and release properly.

Once every system functions correctly, installation is complete.
