How to Install Bifold Doors: Doors That Fold

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.

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

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

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

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.

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.

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.

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