How to Install Bifold Doors

Bifold doors are common for interior doors such as closets. However, bifold doors can also be installed for windows. Installing bifold doors is a simple process that you can do on your own. Read on for a step by step guide on installing bifold doors for your windows.

Take Measurements

Measure the height and width of the opening where you are going to install the doors. If the opening is too high or wide, you may need to add some extra framing to make the doors fit. If the opening is too low or narrow, you will need to trim the doors. Frame the opening with door casing and jambs just like you would an ordinary door.

Adjusting Hinges

Many bifold doors come pre-installed with hinges. However, if you bought bifold doors that have no hinges, you will have to install the hinges on your own. Hinges should be installed 7 inches from the top and 11 inches from the bottom.

Install the Header Track

The header track attaches the doors to the door frame. Centre the header track on the top of the opening and note where the screw holes are positioned. Drill the pilot holes and screw the header track in place.

Set the Pivot Brackets

Insert the pivot bracket to the top of the door and in line with the header track. Pivot brackets should be set ¼ inch from the frame of the door. Align the lower pivot brackets with the hardware that is on the floor. Ensure the bottom pivot bracket is aligned with the top bracket using a plumb bob.

Insert the Pins and Adjustable Pivots

Bifold doors come with nylon guide pins and adjustable pivots. Fix the pins to the pre-drilled holes on top of the door. Fix the adjustable pivots to the pre-drilled holes on the bottom of the door.

Install the Doors

Fold the doors in half and fit the guide pin on the header track. Lift the door and fit the adjustable pivots in the pivot brackets below. Make sure your doors are level using a plumb bob. If the door is not plump or level, you can make adjustments by rotating the lower track sockets and pins until you achieve the right position.

Fix the Door Knobs

Drill holes in the middle of the doors. The ideal position to fix your knobs is 36 inches from the floor. The holes should be the same size as the door fastener. Insert the screws from behind the door to secure the doorknob. Attach the door knob and screw it in.
