Bifold doors are a great alternative to bi-pass doors because they offer greater access and to conventional swing doors that need much more floor space to fully open. Bifold doors are perfect for pantries, bedroom and laundry closets or as a simple room separation. The procedure for installing a typical 36-inch two-panel bifold door can be adapted to wider openings by simply mirroring the installation for the additional door required.

  1. 1

    Use a tape measure to mark the centre line the top horizontal surface of the door opening. Mark the centre at both top corners of the opening and use a straight edge or level to connect the two marks. This establishes the top track mounting line.

  2. 2

    Transfer this centre line to the bottom of the door opening on the pivot side with a builders level. Only mark the bottom of the wall. The line does not need to be continuous.

  3. 3

    Measure the width of the opening and mark this dimension on the metal top track.

  4. 4

    Cut the top track to the length with a hacksaw. Be certain to cut the end of the track opposite the top pivot bracket installed inside the track.

  5. 5

    Position the top track against the horizontal surface at the top of the door opening, centring the screw holes in the track on your line. Attach the track to the top of the opening with the screws provided, inserting a screw in every hole.

  6. 6

    Install the door's bottom pivot bracket in line with the lower centre line. Position the bracket with the short upturned angle against the wall and the notched pivot slot perpendicular to the face of the opening. Attach to the floor and base of the wall with the screws provided.

  7. 7

    Lay the bifold doors on the floor, face up and unfolded.

  8. 8

    Insert the spring-loaded top pivot pin in the top predrilled hole in the door nearest the pivot side of the door. If this hole is not predrilled, follow the door manufacturer's template to drill all of the pivot holes required.

  9. 9

    Insert the spring-loaded guide roller in the top hole at the opposite side of the door.

  10. 10

    Insert the adjustable bottom pivot pin in the predrilled hole in the bottom of the door on the pivot side.

  11. 11

    Stand the door upright next to the opening. Lift the door into place by inserting the top spring-loaded pivot pin in the hole in the top track pivot bracket, then swing the base of the door in to where the notched adjustable bottom pivot drops into the floor bracket installed earlier. Depress the spring-loaded guide wheel to insert it into the top track.

  12. 12

    Close the door and measure the distance between the edge of the door and the face of the door opening at both the top and bottom of the door. This measurement should be the same on both sides of the door.

  13. 13

    Adjust the door's side spacing by lifting the bottom at the pivot and move the door position in the bracket to the desired gap. Open the door slightly and loosen the lock screw in the top pivot bracket to move it to the desired position, then retighten.

  14. 14

    Adjust the door height by lifting the door slightly at the bottom pivot and turning the adjustable bottom pivot pin in or out as needed.

  15. 15

    Measure approximately 36-inches from the centre of the guide door that moves across the opening to close the door and does not have the top and bottom pivots, and centre the mark in the middle of the door panel. Drill a 3/16-inch hole horizontally through the door and attach the door handle by passing the handle screw provided through the hole from the back and screwing the handle on to it until tight.
