How to Fix Closet Folding Doors: Pivots, Track, and the Repair Kit
A bifold door that pops out, drags or will not close is nearly always a worn pivot, a loose bracket or a bent track. Reset it, then replace what failed.

Quick answer
A folding closet door hangs from a top pivot that rides in a metal track, and turns on a bottom pivot set in a floor bracket. When it pops out, drags or will not close flat, one of those parts has slipped, worn out or lost its screw grip. Lift the door out, reseat both pivots, set the bottom pivot height and straighten any bend in the track. If a plastic pivot or guide wheel is cracked, a bifold repair kit replaces all the small parts at once.
Free fix vs. permanent fix
Reseat, adjust and wax the track
- Lift the door out and look at both pivots
- Turn the bottom pivot to set the door height
- Straighten a bent track with pliers
- Rub a candle stub along the track, or use dry silicone spray
How long it lasts: Weeks to years, if the parts are sound. Worn plastic and bent brackets pop out again.
A bifold door repair hardware kit
Pivots and guide wheels are small and often plastic. After years of opening and closing they crack, round off or lose their grip, and the door falls out again however carefully you reseat it. A kit swaps in a fresh set of moving parts, often with metal pivots, so you fix the cause and not just the symptom.

Why it happens
A worn or cracked top pivot or guide wheel
The top pivot rides in the track. It is often plastic, and with years of use it wears or cracks, letting the door pop out when you pull it.
A bottom pivot set too high or too low
The bottom pivot threads up and down. If the door sits too low it drags on the floor or carpet. If it sits too high, the top pops out of the track.
A bent or dirty track
A knock can bend the track, and dust or paint drips can clog it. Either makes the pivot catch and jump.
Loose or stripped screws
Pivot brackets screw into a hollow-core door, where screws strip out easily. A loose bracket lets the door lean and slip.
Loose hinges between the panels
The hinges that join the two panels can loosen, so the panels no longer line up when the door closes.

Do these in order, starting with the simplest.
-
Lift the door out
Lift the door up slightly and swing the bottom pivot out of its bracket, then free the top pivot from the track. Do not force it. Lay the door flat or lean it safely out of the way.
-
Look at the pivots and the track
Tool used: PliersCheck for cracks, a bent pivot pin, a guide wheel that does not turn, and a track that is bent or gunked up. Straighten a bent track gently with pliers and wipe out debris.
-
Re-anchor loose brackets
Tool used: Wood glue and toothpicksTighten the pivot bracket screws. If one spins, pack the hole with wood glue and toothpicks, let it set, trim them flush, then drive the screw in again.
-
Wax the track
Tool used: Candle or dry silicone sprayRub a candle stub along the track, or spray a little dry silicone. Avoid oil or grease, which pick up dust.
-
Rehang the door and set its height
Tool used: Phillips screwdriverSet the bottom pivot in its bracket first, lift the door slightly and tip the top pivot into the track. Turn the bottom pivot up or down until the door hangs level, clears the floor with a small gap and sits flush with the jamb.
-
Replace what is cracked
Tool used: Bifold door repair hardware kitIf a pivot, wheel or bracket is cracked or will not hold, order a repair kit that matches your door's track and pivot style. A mismatch is the main reason kits fail.

When free fixes aren't enough
If a door keeps popping out after you reseat it, the plastic pivot or guide wheel is worn, and adjusting will not bring the grip back. A repair kit gives you new top and bottom pivots, a guide wheel and brackets for a few dollars, which is much cheaper than a new door. If the door is heavy solid wood, or the track is badly bent or has pulled away from the jamb, a heavy-duty set or a new track is the fix. If the door itself is warped or the frame has shifted, a carpenter should look at it.

Bifold door repair hardware kit
Fixes: a bifold door that pops out, drags or leans
Look for: Includes top and bottom pivots, a guide wheel and brackets; Fits your pivot pin size and track, so measure the old parts first; Listed for your door weight, hollow-core or solid; Metal pivots rather than thin plastic where the listing says.
- Who it's for
- Anyone whose reseated door keeps falling out, or whose pivots are cracked or missing.
- Honest downside
- The track itself is bent beyond repair, or the door is solid and very heavy. Choose the heavy-duty set instead.

- Who it's for
- Someone who has found a single cracked part with everything else in good shape.
- Honest downside
- More than one part is worn. Buy the full kit rather than patching one at a time.

Match the symptom to the part
- Pops out of the track when pulled: a worn top pivot or guide wheel, or a door hung too high.
- Drags on the floor: a bottom pivot that is too low, or a sagging track.
- Leans or will not close flush: loose brackets, loose hinges or uneven height.
- Rattles or squeals: a dry or dirty track, or a worn wheel.
What to skip
Forcing the door, and oil in the track
Do not force a door that has jumped the track or pry the track off the frame. Skip oil and grease in the track, since they pick up dust and gum it up. And do not keep driving screws into a stripped hole. Fill it with glue and toothpicks first.
