Please read instructions & notes thoroughly before installation.
Step 1 Align the Template
- If possible, remove the door from its hinges using a flathead screwdriver and hammer to tap out the hinge pins. Lay the door flat for installation. Tape these instructions (they double as a template) to the door where you want to install this face up.
Step 2 Make the Rough Cutout
- Mark the physical outline of this template with a sharp pencil. Remove this template from the door. With a 5/16th (8mm) or or 3/8” (9,5 mm) drill bit, 5/16” preferred, drill through the corners of the outline with the tip of the bit directly on the outline’s corners.
- Place your jigsaw into the holes and cut along the lines you drew. You should be making a rectangle connecting the center of each of the holes. Cut as straight as possible; aim to not deviate more than 1/8” from the line on either side.
Step 3 Test Fit the Frame Tunnels
- Lay the inside frame face down on the floor.
- Fit the outside frame into the inside frame by first placing the bottom of the outside frame’s tunnel into the bottom-left slot of the inside frame’s tunnel. Next, place the right side of the outside frame’s tunnel into the top-right slot of the inside frame’s tunnel (pictures below show the slots and frame orientation).
- Remove the frames from each other once you are familiar with how they fit together.
Step 4 Align Frame Pieces
- At least one of the four locator posts (small posts extending from the bottom of the frame) should meet the bottom of the cutout, depending on the evenness of the cut.
- Use painter's tape to temporarily hold the inside frame around the door. Place tape all around the frame, tightly adhering it to the frame.
- Ensure that the screw holes in the frame are all visible through the cutout opening.
Step 5 Tape Frame Into Door
- Fit the outside frame into the inside frame. You may need to hold the inside frame to keep it from being pushed out of the door.
- Fit together until both frames are flush with the door. The locator posts of the outside frame do not have to be in contact with the rough cutout.
- Use painter’s tape to temporarily hold the outside frame in the door.
Step 6 Fasten Frames To Each Other
- Place a steel washer onto a frame screw (the 2 ¼” or 1 ¾” screws) and place into one of the four frame screw openings from the inside frame to the outside frame. The inside frame should have the screw head.
- Thread a flanged nut onto the screw by hand, reaching through the frames or around the door. You do not need a washer under the nut. The nut should be on the outside frame. Tighten down with a Phillips-head screwdriver.
- Repeat for all four screws.
Step 7 Seal the Frames
- At this point, there should be a washer visible on the inside frame and a nut visible on the outside frame at each of the four points.
- Remove the tape holding the frames to the door.
- If the frame positions need to be adjusted, loosen each of the screws without removing the nut, make the adjustments, and tighten back down. If necessary, you can use tape again to hold the frames in place while you tighten the screws.
- Ensure the frames are flush with your door and are sturdy.
