Fix a pocket door that rubs or sticks
Reset accessible hanger adjustments and bottom guides so the door clears the floor and closes evenly.
Home · 1–2 hr · Medium
Before you start
Have a helper steady and support the door as required before adjustment. Keep fingers clear of the pocket and jamb. Do not release hanger retainers or work under an unsecured door. Stop for loose track, broken rollers, hidden obstructions or unidentified hardware; do not cut into the wall or install longer screws.
Tools and materials
- Correct thin hanger-adjustment wrench and screwdriver
- Short level, tape measure and flashlight
- Vacuum brush, cloth and eye protection
Check the problem
Locate the rubbing point
Slide the door gently and inspect the floor gap, side rub marks and bottom guides. A tilted edge suggests hanger adjustment; grinding overhead, a dropped corner or loose track needs hardware repair rather than more force.
Check that the adjustment is accessible
Identify the hanger adjusters, retainers and removable header trim from the hardware instructions. Continue only if both hangers remain captured and sound. Stop for a derailed carriage, broken rollers, bent track, swollen door or anything requiring wall opening.
Steps
Protect the area and expose the hangers
Clear the floor and have a helper steady the door. Remove only the screw-fastened access trim specified for your system, keeping its screws together. Do not pry off unknown trim, release hanger locks or cut into the wall.
Clear the accessible track and guides
Brush or vacuum loose debris from the accessible track and bottom guides. Move the door gently to expose the next section. Do not reach blindly into the pocket or spray oil into the track; stop if a wheel or track is damaged.
Correct the floor clearance
Support the door as directed for your hardware. Fit the correct thin wrench on the hanger adjuster and turn it a small amount in the specified direction. Adjust both hangers as needed to clear the floor without exceeding the thread-engagement limit.
Make the closing edge parallel to the jamb
Bring the door nearly closed. Compare its edge with the strike jamb, then adjust one hanger at a time until the gap is even from top to bottom. Keep the floor clearance and required thread engagement; secure any adjustment locks specified by the kit.
Center the door between the bottom guides
Loosen the guide screws just enough to position the guides around the door. Leave the kit’s running clearance so the door slides freely without side-to-side rubbing, then retighten. Guides keep the door aligned; they should not clamp it.
Check retainers and replace the trim
Confirm both hanger connections and their retainers are fully secure without releasing them. Refit the access trim with its original screws in the original holes. Do not substitute longer screws that could enter the door pocket.
Test the full travel and latch
Slide the door fully open and closed several times. It should glide without scraping, stay centered and meet the strike jamb evenly; test the latch without forcing it. If it binds inside the pocket or the adjustment drifts, stop and have the hidden hardware repaired.
The door travels fully in both directions without scraping or grinding, remains centered between its guides, meets the jamb evenly and latches without force. Both hangers remain secure and the adjustment does not drift.
Tips
Separate height from alignment
Small equal changes at both hangers change overall height. A change at one end changes the closing-edge angle. Recheck both after every adjustment.
Keep the access removable
Return the access trim to its original screw holes rather than nailing or gluing it shut. Future adjustments should not require wall damage.
Do not hide a hardware problem
Repeated derailment, rough rollers or a bent track will not be cured by forcing the door higher or adding lubricant. Identify the failed part before planning a different repair.
