Which of the following is the correct sequence for installing a bifold door?

• A. Top track, lower track, insert bottom pivot, insert upper pivot.
• B. Lower track, top track, insert upper pivot, insert bottom pivot
• C. Insert upper pivot, insert lower pivot, top track, bottom track
• D. Top track, insert upper pivot, lower track, insert bottom pivot

Answer: (A)

When installing a bifold door, establish the guiding structure first and then secure the moving parts in a logical order. Putting in the top track first creates the primary guide and supports the door’s weight as it hangs. Next, adding the lower track provides the second axis and helps keep the bottom edge aligned. With both tracks in place, insert the bottom pivot into its bracket and seat it in the lower track to anchor the bottom of the panel. Finally, insert the upper pivot into the top track, securing the panel so it can swing and glide smoothly along both guides. This sequence minimizes binding, ensures proper alignment, and makes installation easier.
