InvisiDoor Installation 101

The InvisiDoor by Custom Service Hardware is one of our most popular products, and it’s no secret why. Our hidden door solutions come ready to install, and installation is easy enough for anyone to handle, only requiring as little as a drill. Check out the video to learn about the benefits of the InvisiDoor, and read on to find out just how easy it is to set up and install!

Required Tools

  • Cordless drill or screwdriver
  • Drill bits: 3/32” and 5/8”
  • Level
  • ¼” Hex driver


Installation Preparation

Check the opening into which the Invisidoor will be installed to verify that it is plumb and level. Correct operation and appearance of the Invisidoor requires that the opening be level and plumb or you need to make accommodations for it.

The Invisidoor pivot hinge is designed to be installed with the bottom hinge plate secured to stable, solid wood. Verify that the floor of the opening has adequate support for weight of the unit and holding power for the screws.

It is recommended that you test mount the hardware and install the Invisidoor prior to applying stain and finishing coat. This will eliminate the chance of damaging the finished product during the process of mounting the hinges and adjusting the unit.


Building the Bookcase

Dimensions given with these instructions are based on the size of the universal InvisiDoor (for standard 36” x 80” finished openings) to assist you in sizing your bookcase and finding the appropriate hinge locations. Modifications to the width or depth of the bookcase will likely require changing the spacing allowed for clearance or location of the hinge pivot point. In all cases, it is recommended that you create a template to mock up the dimensions of the opening and the bookcase to verify that you have the necessary clearance for your door to operate properly.



Design recommendations based on our universal bookcase. Modify design as appropriate for custom applications:

  • Top, bottom, and fixed shelf are dadoed into sides for strength to prevent sagging.
  • Face frame (2-1/4” wide) glued and nailed to carcass.
  • ½” plywood glued and nailed to the back for strength to prevent sagging.
  • Bottom shelf is flush to the face frame (inside the bookcase).
  • Sides and back run down past the bottom shelf, but not as far as the face frame (forms a pocket on the bottom of the bookcase.)
  • Screw 2 mounting blocks into this pocket. The thickness of the blocks may need to be adjusted based on the clearance and spacing needed for the door.
  • Left and right edge of the face frame rounded over with 3/8” radius bit.


Install Hinges to Opening


Use the diagrams to identify locations for the pivot hinge to be installed on the left or right side of the unit as either an outswing (which pulls out toward the bookcase side) or an inswing (which rotates away from the bookcase side). In most cases, the bookcase face frame will be ­flush with the drywall. Trim will later be mounted over the drywall and bookcase face frame, spanning across the jamb.


Walls more than a standard 2” x 4” thick may require modification for an inswing door application.

Use the diagrams to install hinge plate #3 to threshold/floor. Place the two steel washers and bronze bearing onto the hinge pin as shown.


Install a hinge plate #4 to the upper jamb. Shim the jamb as needed at location of pivot hinge for a solid mounting area with longer hinge plate screws mounted into header for final installation.



Install Hinges to Bookcase

Install the mounting blocks (usually two 11/16” blocks on the bottom and one 1/2” on the top) to the hinged side of the bookcase unit. Use blocks of a different thickness to create appropriate height and margin for your application.


Use the mounting diagram to install hinge plate #1 to the bottom of the bookcase.

Prior to installing the upper hinge on an outswing door to the bookcase, an access hole for the set screw must be drilled through the top of the bookcase. Use the diagrams for the location of this hole. (Predrill a small hole from the top of the bookcase. Then drill a 5/8” hole from the inside of the bookcase through the top to avoid tear out inside the bookcase.)


Mount hinge plate #2 to the top of the bookcase. Thread the included setscrew/capscrew into the threaded.



Install the Bookcase

For an outswing door, you will work from the backside of the Invisidoor to put it into place on the lower hinge pin and install the capscrew through the top.

Lift the bookcase into the opening. Set the hinge on the bottom of the bookcase onto the pin of the hinge plate on the threshold. Align the upper hinges and screw the set screw into the hinge plate on the header. Use of Locktite can prevent set screw from twisting loose over time.

Verify the fit of the trim against the installed Invisidoor. A slight gap between the bookcase and face frame is necessary to allow clearance for the bookcase to swing. Adjust hinges as needed by using slotted holes in hinge plates. Predrill holes for remaining screws for each of the hinge plates. The provided 2-1/4” screws will be used to secure hinge plate 4 through the upper jamb into the door header.


Install Support Foot

Mount bracket to the side of bookcase. Bracket must be attached near the face frame to allow enough clearance to swing past the jamb. Align the tapered stop to the location of the bolt when the door is in the closed position, mark the location, fasten it with the supplied tape/and or screw.



Install Trim


Trim on both sides and the top of the door are mounted to the wall and serve as a stop for the door. Avoid using trim that has a narrow inside edge as it will not hold up as a stop. A 3/4” thick molding is recommended. It is also recommended that the trim overlay the face frame by 1/2”- 3/4”.

A wide variety of trim styles will work for the inswing mounted Invisidoor. Corner blocks, mitered corners, or built out crowns can all be used without interfering with the function of the door.



Trim on the hinge side of the bookcase and the top will be attached to the wall, but the non-hinged side trim will be attached to the bookcase to act as a stop. It is recommended that the trim overlay the face frame by 3/4” and be mounted very securely to withstand the opening and closing of the door. The trim across the top of the door must be mounted to allow clearance for the door to swing below it. Also, allow clearance for the door-mounted trim to swing freely from the upper piece of trim as well as clear the floor.


Finish the Bookcase

Remove Invisidoor from the opening and remove hinge plates from the case. Do a final sanding of project. Apply stain and finish coat of choice according to manufacturer’s directions. Reinstall hinges by mounting all screws. Reinstall InvisiDoor into opening and permanently install trim.

  1. I bought this thing years ago and don’t have the expertise to install it.
    A few others said they would but then were never available to do it.
    Do you know of anyone that knows what they are doing and can install this. At
    this time even an unreasonable price would be considered.
    I wanted this thing for my panic room . So please advise anyone, interested in
    this project.

  2. We have door openings that go to an attic space the doors are around 48″ high and 30-32 wide. I need to know
    1. How much smaller does the jam need to be compared to the bookcase I make.
    2. What will width of the opening be with an 8″ book shelf. In other words how much opening space do u loose with the hinges? And is it any difference with in or out swing.
    3. Can adhesive strip insulation be added around door?

    1. 1. Our standard doors are 1 inch narrower and 1-1/8 inch shorter than the finished opening. You may need to leave additional clearance if narrower than 32 inches or if the depth is more than 8 inches.
      2. You will lose about 11-1/2” for an outswing and 8” for an inswing.
      3. It would be possible and should work better on an inswing because it closes up against the trim instead of having part swing in and part swing out.

      Hope this helps! Let us know if you have any more questions

  3. Hi,
    I have an invisidoor installed already. We are moving and I want to take the safe with me. What is an easy way to take door off and put back in without tearing everything up? Thanks! David

    1. Thanks for your question! The method for removing the door depends on a bit on whether it’s an inswing or outswing version.

      The inswing is easier – just remove the large machine screw in the back and lift the bookcase off the bottom pin (after clearing the shelves, of course).

      For an outswing, you’ll likely have to remove the piece of trim above the door. Then remove the machine screw through the ceiling of the bookcase with an allen wrench, and you’ll be able to lift the door off the lower pin.

      Hope this helps!

      1. My name is abdulaziz . i have purchased INVISIDOOR HINGE KIT from amazon and i would like to use it to do outswing book case cabinet . i have the dimension of the oppening as follow ,
        l:213 cm
        w: 93.5 cm
        depth : 24 cm

        what will the gap between the frame and the book case and where is suppose to install the hinges

        1. Hi Abdulaziz, thanks for your question!

          It looks like your dimensions are slightly wider and deeper than our standard bookcase so you will likely need a bit more space for clearance than we suggest in our instructions for our standard bookcase. It will also depend on how you construct your bookcase, especially if you use a face frame wider than the bookcase carcass as we do.

          I would recommend that you create a cardboard template of the footprint of the bookcase size that you intend to build. You can then use a pine or nail to act as a pivot point to see if that design for a bookcase will clear your opening. Adjust the size of the bookcase or the location of the pivot point as needed.
