To install your four-panel bifold door that folds to both sides with a thickness of 1-3/8 inches, you can follow these summarized instructions derived from several comprehensive resources. Here’s a step-by-step guide:

Preparation

1. Gather Tools and Materials: Ensure you have all the necessary tools—like a drill, screwdriver, level, tape measure, and any included hardware for installation.

2. Measure the Opening: Measure the height and width of your finished wall opening. Ensure it is appropriate for a four-panel bifold door. The opening should not be more than 1/4 inch larger or smaller than the dimensions stated on the door packaging.

Installation Steps

3. Prepare the Doors:

   • Lay the bifold doors, face down, on a flat surface.
   • If joining multiple doors, ensure they are butted together with a 1/32 inch gap in between to allow for proper movement.

4. Install the Top Track:

   • Mark the spot where the top track will be installed, maintaining the correct height.
   • Use a level to ensure the track is straight, then drill holes and mount the track to the wall.

5. Attach Pivots and Hinges:

   • Install the top pivots in the designated locations on your bifold doors (generally at the top edge). Follow instructions specific to door hardware for aligning these properly.
   • Secure the bottom pivots to the corresponding locations on the bottom edges of the doors.

6. Align and Install the Doors:

   • Position the doors in the opening, lifting the top pivots into the track.
   • For a four-panel configuration, align the doors properly; ensure they fold correctly to both sides.
   • The alignment aligners should be attached approximately 12 inches from the floor, ensuring they fit snugly yet allow for the door's motion.

7. Install the Bottom Track and Bracket:

   • Install the bottom track according to the provided specifications, ensuring the track aligns correctly with the top track.
   • Various sources suggest mounting the bottom bracket so that the center of the serrated hole is aligned vertically with the center of the top track.

8. Final Adjustments:

   • Check that the doors operate smoothly—adjust pivots and aligners as necessary to ensure they fold and open properly.

9. Finishing Touches:

   • If desired, paint or finish your doors before they are fully installed for a polished look.
