Prepare to Install Bi-fold Doors

Instructions

Step 1

Man measuring the closet opening

Remove the old doors and hardware. Then measure the closet opening. Use this to check the size recommendations when buying new doors.

Good to Know

For smaller openings, consider using a single bi-fold door.

Step 2

Repair the door opening as needed, such as filling old screw holes and painting.

Step 3

Mark the center of the opening

To help position the new doors in the opening, lightly mark the centers of the closet. Use a level to mark plumb lines on the sides of the jambs.

Install the Track and Brackets

Instructions

Step 1

Bi-fold doors work with a track and brackets. Cut the track to leave a 1/16-inch gap on either end. Then install the track – centered on the top of the frame (header) – with the pivot bracket toward the jamb.

Step 2

Center the jamb bracket at the floor. Drill pilot holes and then fasten the bracket to the jamb with screws.

Install the Doors

Instructions

Step 1

Before installing the hardware, paint the doors. It's easiest to paint them on sawhorses.

Step 2

When the doors are dry, use a hammer to lightly tap the pivots into the holes at the top and bottom.

Step 3

Install the doors by inserting the top pivots into the brackets. Then seat the bottom pivots.

Step 4

Insert the snugger guide (the plastic white round piece that's shown in the picture) into the track. Then squeeze the guide pivot on the top of the door, position it under the track, and release it, making sure the guide pivot is securely in the track.

Adjust the Doors

Instructions

Step 1

Check the door height. The doors shouldn’t rub on the floor or come in contact with the header jamb. To change the height, lift the door and rotate the bottom pivot.

Step 2

To make it plumb, lift the door and slide it into the desired position on the jamb bracket. Loosen the screw in the top pivot bracket and slide it until the door is plumb and then tighten.

Attach the Hardware

Instructions

Step 1

Some bi-fold doors include pulls, but you can also install decorative hardware to complement the other doors.

To install decorative pulls, mark a comfortable height on the face of the guide door – centered is usually best for ease of use. Hold the hardware in place, marking the holes. Then secure the hardware.

Step 2

Aligners help keep the doors closed. From inside the closet, loosely attach them on the back of the doors about 12 inches from the floor. Adjust in or out so the doors snap closed. Then tighten the screws.

Step 3

Make sure the doors are working properly and make adjustments if needed.
