Preparing And Hanging The Door
Careful preparation protects the door, makes adjustment easier, and prevents hard-to-reach problems after the wall is closed. Use this guide to prepare, hang, align, and test a single or double pocket door.
A pocket door should be prepared and test-hung before access to the track and pocket is restricted. The exact plate locations, fasteners, clearances, and adjustment method vary by system, so keep the instructions for your door and hardware beside you while working. Manufacturer dimensions always take priority over general guidelines.
Safety First
Door slabs—especially solid-core, glass, mirrored, or oversized panels—can be heavy and awkward. Use two people or appropriate lifting equipment. Support the door until both hangers are fully engaged and locked. Wear eye protection, follow the door manufacturer’s cutting and drilling instructions, and never work beneath an unsupported panel.
What Must Be Confirmed Before Hanging
Door and Hardware
- The slab width, height, and thickness match the frame kit.
- The complete door weight is below the hardware rating.
- The top and edges contain enough solid material for the plates, pull, and lock.
- The panel is reasonably flat, square, and free of shipping damage.
- Rollers, plates, fasteners, stops, guides, adjustment wrench, and optional accessories are present.
Frame and Opening
- The track is straight, clean, securely fastened, and level.
- The pocket studs are plumb, parallel, and not bowed inward.
- The pocket is free of screws, debris, wiring, and other obstructions.
- The finished-floor elevation is known.
- The planned guide, stops, jambs, casing, pull, and lock will not interfere with travel.
Do Not Guess at Door Clearance
Required space below the slab depends on the frame, hanger adjustment range, bottom guide, flooring, rug clearance, and any threshold. Measure from the installed track to the completed floor surface, then compare that measurement with the exact hardware instructions. If finish flooring is not installed, include its full thickness.
Prepare the Door Slab
-
Identify the Door Faces and Edges
Decide which face will be visible from each room, which vertical edge will close against the jamb, and which edge will enter the pocket. Mark the top lightly with removable tape. This prevents installing plates, locks, edge pulls, or a bumper on the wrong side.
-
Make Any Approved Size Corrections
Check the slab against the required finished size before attaching hardware. Trim only where and by the amount allowed by the door manufacturer. Hollow-core, molded, fire-rated, glass, and veneered doors may have strict limits. A pocket-door frame is not a substitute for correcting an oversized or out-of- square slab.
-
Seal All Six Sides
Apply the specified paint, clear finish, or sealer to both faces and all four edges—including the top and bottom. Balanced finishing helps reduce uneven moisture absorption and warping. Allow the finish to cure before laying out hardware or sliding the door into the pocket.
-
Prepare the Pull and Lock
Use the hardware template and verify the backset, height, door-thickness range, and edge orientation. Drill or rout carefully so the pull or lock sits flush and cannot catch the split jambs. If the door is hollow-core, confirm that solid blocking exists where the hardware will be installed.
-
Protect Finished Surfaces
Place the slab on padded supports, keep tools and metal shavings off the faces, and protect sharp corners. Do not use tape that can lift uncured paint or clear finish.
Lay Out and Install the Top Hardware
The door plates transfer the entire door load to the hangers. They must be positioned as directed, centered across the door thickness, and fastened into sound material.
- Read the plate orientation. Identify the locking clip or open end of each slot. If the system requires both slots to face the same direction, arrange them before marking holes.
- Measure from the ends of the door. Use the dimension in the hardware instructions; do not assume every brand uses the same setback.
- Center each plate. Draw a centerline along the top edge and align both plates consistently so the panel hangs beneath the track without twisting.
- Mark and drill pilot holes. Use a bit sized for the supplied fasteners and the door material. Control drill depth so the bit cannot break through a door face.
- Fasten securely. Keep the plates flat and avoid stripping the holes or overtightening into soft material. Load-bearing plates cannot rely on thin veneer or door skin alone.
HBP Series 1 Frame-Kit Detail
For the current HBP frame-kit instructions, place each door plate 2¾ inches from its end of the door and orient both plate slots in the same direction. Insert the 4-wheel hangers into the track with each hanger bolt initially in its lowest position. These dimensions are system-specific; use the instructions supplied with your exact kit if they differ.
Load the Track Before the Opening Is Restricted
Insert every component that must travel inside the track—hangers, stops, soft-close or soft-open parts, and any required retainers—in the order and orientation shown by the manufacturer. Confirm that each roller moves freely. Adding a missed component later may require removing trim or opening the wall.
How to Hang the Pocket Door
-
Set the Hangers for Maximum Initial Clearance
Move both adjustment bolts to the starting position specified for the hardware. Beginning with the door at its lowest practical setting usually provides room to connect the plates and then raise the slab gradually.
-
Bring the Door Into the Opening
Keep the panel upright and supported on padded shims, a door lifter, or a second person. Do not drag a finished edge across the subfloor. Align the plate nearest the pocket with its hanger first when the hardware instructions call for that sequence.
-
Connect the First Hanger
Guide the hanger pin or bolt completely into the door-plate slot. Close the clip, clasp, or locking tab fully. Continue supporting the door; one connected hanger is not enough to carry or control the panel safely.
-
Connect and Lock the Second Hanger
Move the second hanger into position, engage it completely, and lock its retaining part. Visually and physically confirm both connections before removing the shims or lifting support.
-
Move the Door Slowly by Hand
Roll the slab only a short distance at first. Stop immediately if it scrapes, tilts, catches, or if a hanger appears loose. Correct the problem while the panel remains easy to reach.
For HBP Series 1 Hardware
Engage the pocket-end plate first, then the opening-end plate, and close the clasp on each plate to lock the hanger bolt in position. Adjust height with the hex nut on the hanger bolt. Never operate the door with either clasp open.
Level, Center, Guide, and Stop the Door
Adjustment is a sequence: first establish height, then level the slab, then center it within the pocket, and finally set the guide and travel limits. Changing one item can affect the others, so recheck the complete system after every major correction.
| Check | What Good Alignment Looks Like | Correction |
|---|---|---|
| Height | The bottom clears the completed floor and the top does not rub the header or trim. | Raise or lower both hangers in small, equal increments. |
| Level | The top and bottom edges are level and the closing edge meets the jamb evenly. | Adjust one hanger slightly; recheck height afterward. |
| Plumb | The closing edge is parallel to the finished jamb from top to bottom. | Verify the frame and jamb first, then fine-tune hanger height. |
| Pocket Clearance | The door travels without rubbing either pocket wall or any fastener. | Check plate centering, guide position, bowed studs, and protruding screws. |
| Travel | The door opens far enough for the intended clear passage and closes at the correct point. | Set the stops and bumper without forcing the rollers into the track ends. |
Install the Bottom Guide
The guide controls side-to-side movement; it should not carry the door’s weight. Place it at the pocket entrance or at the system’s specified location. Adjust it close enough to stabilize the slab but not so tightly that it scratches the finish or creates drag. Confirm that screws will not damage flooring, tubing, wiring, or radiant heat below.
Set the Bumper and Stops
Position the rear bumper so the door cannot strike the back of the pocket. Set track stops so the pull, lock, slab, hangers, and any soft-motion hardware are protected at both ends of travel. HBP’s current frame-kit instructions place the supplied rubber bumper on the back edge of the door, 40 inches above the bottom; follow the directions for your exact kit.
Adjust Soft-Close, Soft-Open, or Push-Release Hardware
Install and test controlled-motion accessories according to their separate instructions. Make sure the actuator engages positively but does not collide with the hanger, stop, or track fastener. A door should roll smoothly by itself before an accessory is expected to control its movement.
Special Notes for Double Pocket Doors
- Prepare, hang, and level each door independently before trying to align the center meeting edges.
- Match the finished floor clearance and reveal on both panels.
- Bring the doors together and compare their full-height meeting edges. Correct panel level and jamb plumb before adjusting a converging connector.
- Install any converging-door hardware only after both doors operate freely throughout their full travel.
- Check that pulls, locks, and stops are mirrored correctly and that neither door can push the other beyond its intended limit.
Common Problems After Hanging
| Problem | Likely Causes | What to Check First |
|---|---|---|
| Door rolls open or closed by itself | Track is not level or the frame shifted during fastening. | Check the track with a reliable level before changing stops or hangers. |
| Closing edge is uneven at the jamb | Door is not level, jamb is not plumb, or one hanger is set too high. | Compare the slab with both a level and the jamb; adjust in small increments. |
| Door rubs inside the pocket | Off-center plates, incorrect guide position, bowed framing, debris, or a protruding screw. | Stop operating the door and inspect the pocket before the finish is damaged. |
| Bottom swings sideways | Guide is missing, loose, too wide, or incorrectly located. | Reposition and secure the guide without pinching the slab. |
| Door is hard to move | Guide friction, dirty or damaged track, overtight fit, misaligned roller, or excess door weight. | Disconnect optional motion hardware and isolate the source of resistance. |
| Door will not open or close fully | Stop, bumper, pull, lock, or soft-motion component is incorrectly positioned. | Observe where travel ends and compare every component with its installation diagram. |
Final Test Before Closing the Wall
- Move the door through at least 10 complete open-and-close cycles.
- Confirm both hanger locks remain fully engaged.
- Verify smooth, quiet travel with no rubbing or rolling by itself.
- Check the top, bottom, jamb, and pocket clearances throughout the full travel.
- Test the guide, stops, bumper, pull, lock, and optional motion hardware.
- For double doors, confirm even center alignment and independent operation.
- Mark the pocket zone so later drywall, trim, cabinet, and accessory fasteners cannot enter it.
- Photograph the open framing and hardware locations before covering them.
