Pocket and Sliding Interior Doors
Summary
Pocket and sliding interior doors are leaves hung from overhead tracks that slide into a framed wall pocket, along the wall face, or past each other in bypass layouts. They save floor space where door swings conflict with clearances, but pocket depth, hardware access, acoustic and fire limits, and accessible pulls must be planned in the wall layout.

Terminology
- Pocket frame: split studs and header track kit forming the cavity the door slides into
- Split jamb / split stud: paired steel-wrapped wood or steel studs on each side of the pocket
- Header track: aluminum or steel track carrying the hangers
- Hanger / trolley: wheeled carriage screwed to the top of the leaf; 2, 3, or 4 wheels
- Floor guide: bottom guide keeping the leaf aligned; no floor track on pocket doors
- Soft close / soft open: damper that slows the leaf at the end of travel
- Edge pull / flush pull: recessed pulls that let the leaf retract fully into the pocket
- Surface slide (barn door): leaf hung on an exposed track on the wall face
- Bypass: two or more leaves on parallel tracks sliding past each other
- Bi-parting: two leaves meeting at the center of the opening
- Telescoping: linked leaves on parallel tracks moving together to open wider
- Header access panel: removable trim or panel for servicing hangers without demolition
Standards
Sizes
- Leaf thickness: 1-3/8 in. or 1-3/4 in.; heavy-duty frames carry both
- Common leaf sizes: 2'-6" to 3'-6" wide by 6'-8" to 8'-0" high; taller with heavy-duty commercial frames
- Pocket wall length: at least twice the leaf width plus jamb allowances; confirm rough opening with the frame kit
Ratings
- Hardware load ratings: 75 lb to 125 lb for standard residential kits; 200 lb and higher for heavy-duty and commercial track
- Fire-rated sliding doors are limited to specific listed assemblies; standard pocket frames are not rated
- Acoustic performance is limited by perimeter gaps; sealed sliding systems needed for STC targets
Test standards
- ANSI/BHMA A156.14: sliding and folding door hardware
- ANSI/BHMA A156.38: low-energy power-operated sliding and folding doors, where automated
- ASTM E90: sound transmission for tested sealed systems
Types
| Type | Wall impact | Acoustic and privacy | Key coordination |
|---|---|---|---|
| Needs a pocket wall free of pipes, conduit, and blocking | Low | Wall thickness, services, header access | |
| Surface slide (barn) | Exposed track on wall face; wall stays solid | Low, open gaps at edges | Wall clear width beside opening, blocking for track |
| Bypass | No pocket; half the opening stays blocked | Low | Common for closets |
| Bi-parting pocket | Two pockets, one each side | Low | Double pocket wall length |
| Glass sliding systems | Top-hung aluminum frames with glass leaves | Moderate with seals | Ceiling or header structure |
Materials
- Leaves: flush wood, stile and rail, glass in aluminum frames, or MDF; solid cores add weight
- Pocket frames: steel-wrapped wood split studs or steel stud kits; steel kits for metal stud walls
- Track: extruded aluminum or steel; stainless or black finishes for exposed surface tracks
- Rollers: nylon or ball-bearing steel wheels for quiet operation
- Pulls: recessed flush pulls, edge pulls, and surface pulls; accessible pulls with full hand clearance
Uses
Specific uses
- Residential bathrooms, closets, and pantries where swings conflict with fixtures
- Accessible toilet rooms and dwelling units needing clear floor space
- Healthcare patient toilet doors and exam rooms
- Office and conference fronts with glass sliding panels
- Hospitality suites dividing sleeping and living areas
Pros and cons
Pros
- Frees the swing area for clearances and furniture
- Leaves the opening fully clear when open
- Surface sliders work in existing walls without a pocket
- Wide variety of leaf materials and finishes
Cons
- Pocket walls cannot hold plumbing, outlets, switches, or grab bar blocking within the pocket length
- Poor acoustic and visual privacy from edge gaps
- Hardware is hard to service without an access header
- Recessed pulls are often hard to grasp; compliant hardware needs careful selection
- Standard assemblies are not fire-rated
Manufacturing and cost
Construction
- Header track and split studs installed during framing; leaf hung after finishes
- Pocket walls finished with drywall screwed into split studs using short screws to avoid damaging the leaf
- Surface tracks anchor to continuous blocking or a header board sized for door weight
- Hardware adjusted for level, plumb, and gap; floor guides set after flooring
