定制柜安装工艺 — Custom Cabinet Installation Craft
1. Overview
Custom cabinet installation is a multi-stage process that begins with precise site measurement and extends through production, delivery, on-site assembly, leveling, door adjustment, hardware mounting, and final finishing. This guide covers the complete workflow for residential built-in cabinets including wardrobes, kitchen cabinets, TV units, and storage systems.
2. Site Measurement (现场测量)
2.1 Measurement Tools Required
| Tool | Purpose | Accuracy Required |
|---|---|---|
| Laser distance meter | Room dimensions, ceiling height | ±1 mm |
| Steel tape measure (5 m) | Cabinet-level dimensions | ±1 mm |
| Digital level / inclinometer | Wall plumb, floor level | ±0.5 degrees |
| 2 m straightedge | Wall flatness check | Visual + gap measurement |
| Square (90 degrees) | Corner angles | Visual |
| Digital camera | Document site conditions, obstacles | N/A |
| Graph paper / CAD software | Record measurements | N/A |
2.2 Measurement Checklist
- [ ] Room length, width, and ceiling height (measure at multiple points)
- [ ] Wall flatness: check each wall at top, middle, and bottom
- [ ] Wall plumb: check each wall for out-of-plumb condition
- [ ] Corner angles: verify 90-degree corners (many are not exactly 90)
- [ ] Floor levelness: check across the entire cabinet run
- [ ] Location of electrical outlets, switches, and data ports
- [ ] Location of water supply lines, drain pipes, and gas lines
- [ ] HVAC vents, radiators, and heating pipes
- [ ] Window and door positions, including swing direction
- [ ] Ceiling features (beams, soffits, dropped ceilings)
- [ ] Baseboard height and profile (if cabinets sit on floor)
- [ ] Ceiling crown molding or trim (if cabinets reach ceiling)
2.3 Critical Tolerance Values
| Measurement | Maximum Tolerance |
|---|---|
| Wall flatness | 3 mm over 2 m |
| Wall plumb | 3 mm over 3 m height |
| Floor levelness | 3 mm over 2 m |
| Corner squareness | 90 ± 1 degrees |
| Ceiling height variation | 5 mm across room (note for scribe) |
2.4 Measurement Documentation
For each cabinet location, document:
- Plan view sketch with dimensions
- Elevation view showing height, shelf positions, and features
- Photo documentation of the area from multiple angles
- Obstacle log listing all pipes, outlets, and obstructions with dimensions
- Adjacent furniture/fixtures that may affect installation

| 2 | Locate wall studs | Mark stud positions; verify with stud finder |
| 3 | Position first cabinet | Place in corner or at designated start point |
| 4 | Level the cabinet | Use shims under cabinet base; check level front-to-back and side-to-side |
| 5 | Secure to wall | Drill through cabinet back rail into wall studs; use minimum 50 mm screws |
| 6 | Install adjacent cabinets | Clamp together, verify alignment, fasten with connector screws through side panels |
| 7 | Join cabinets | Use cabinet connector bolts or screws through pre-drilled holes; install cam locks if provided |
| 8 | Install toe-kick | Attach after all base cabinets are level and secured |
Phase 2: Wall Cabinet Installation
| Step | Action | Detail |
|---|---|---|
| 1 | Mark reference lines | Bottom of wall cabinets typically 1350-1450 mm from floor (to bottom of cabinet) |
| 2 | Install hanging rail (if using rail system) | Level and secure rail to wall studs |
| 3 | Hang cabinets | Hang on rail system or mount directly to wall studs |
| 4 | Level and plumb | Adjust hanging brackets; check with level |
| 5 | Join adjacent wall cabinets | Clamp, align, and fasten with connector screws |
| 6 | Fill gaps to ceiling | Install scribe/crown molding or filler strip as needed |
Phase 3: Tall Cabinet Installation

| Overall run alignment | 2 mm over 3 m |
6.2 Shim Placement Guide
| Location | Purpose |
|---|---|
| Under cabinet base (front) | Correct front-to-back level |
| Under cabinet base (sides) | Correct side-to-side level |
| Between cabinet and wall (back) | Correct for out-of-plumb walls |
| Between cabinets (top/bottom) | Correct for height mismatches between units |
Important: Shims must be placed directly under structural points (corners, divider panels), not in the middle of unsupported panels.
7. Door and Drawer Adjustment
7.1 Hinge Adjustment (3-Way)
| Adjustment | Screw Location | Effect |
|---|---|---|
| Depth (in/out) | Rear screw on hinge arm | Moves door closer to or farther from cabinet |
| Height (up/down) | Mounting plate screws | Moves door up or down |
| Side (left/right) | Front screw on hinge arm | Moves door left or right; closes or opens gap |
7.2 Door Gap Specifications
| Gap Type | Recommended Size |
|---|---|
| Between adjacent doors | 2-3 mm |
| Between door and cabinet frame (side) | 2 mm |
| Between door and cabinet frame (top/bottom) | 2-3 mm |
| Overlay door to edge of cabinet | Per door design (full, half, or inset overlay) |
7.3 Adjustment Procedure
- Loosen the adjustment screws slightly (do not remove).
- Adjust one screw at a time; close door to check alignment.
- Tighten all screws once alignment is correct.
- Check operation: door should open and close smoothly without binding.
- Verify gap consistency across all doors in the same run.
7.4 Drawer Alignment
| Issue | Adjustment |
|---|---|
| Drawer front not level | Adjust slide mounting position or front panel mounting screws |
| Drawer not closing smoothly | Check slide alignment; lubricate; verify no obstructions |
| Drawer front offset from adjacent door | Adjust front panel on drawer box mounting brackets |
| Soft-close not engaging | Check slide installation; verify drawer is fully seated on slides |
8. Hardware Installation
8.1 Hardware Installation Sequence
| Order | Hardware | Notes |
|---|---|---|
| 1 | Hinges | Mount to door first, then to cabinet |
| 2 | Drawer slides | Mount to cabinet first, then to drawer |
| 3 | Drawer fronts | Attach to drawer box after slides are installed |
| 4 | Handles/pulls | Mark, drill, and mount after all doors are aligned |
| 5 | Internal accessories | Shelf pins, clothes rods, pull-outs, organizers |
| 6 | Soft-close dampers | Add to cabinets without soft-close hinges |
| 7 | Lighting (LED strips, puck lights) | Wire and mount in pre-planned locations |
| 8 | Lock mechanisms | Install on designated doors/drawers |
8.2 Handle/Pull Placement
| Cabinet Type | Placement | Distance from Edge |
|---|---|---|

| 1 | Mark hole positions using template or measuring from edges |
| 2 | Verify both sides (front and back) of drilling location |
| 3 | Use appropriate drill bit for handle screw diameter |
| 4 | Drill from the finished face side to prevent tear-out |
| 5 | Apply masking tape at drilling location for clean entry |
| 6 | Deburr hole edges |
| 7 | Install handle with screws (do not overtighten) |
9. Gap Filling and Finishing
9.1 Gap Types and Treatments
| Gap Location | Width | Filling Method |
|---|---|---|
| Cabinet top to ceiling | 0-30 mm | Crown molding, filler strip, or scribe |
| Cabinet side to wall | 0-20 mm | Scribe strip (cut to match wall contour), caulk |
| Between adjacent cabinets | 0-1 mm | Connector strip, caulk (painted cabinets) |
| Base cabinet to floor | 0-15 mm | Toe-kick board (adjustable or fixed) |
| Around pipes/conduits | Varies | Decorative escutcheon plate + caulk |
| Corner (cabinet to wall) | Varies | Caulk (color-matched) |
9.2 Scribe Strip Installation
A scribe strip is a narrow piece of material (typically 50-80 mm wide) used to fill the gap between a cabinet and an uneven wall.
| Step | Action |
|---|---|
| 1 | Cut scribe strip slightly wider than the maximum gap |
| 2 | Place against cabinet, flush with cabinet face |
| 3 | Use a compass or scribe tool to transfer wall contour onto the strip |
| 4 | Cut along the scribed line with a jigsaw |
| 5 | Test fit against the wall; trim as needed |
| 6 | Attach to cabinet with adhesive and/or finish nails |
| 7 | Caulk the seam between scribe and wall |
9.3 Caulking Guidelines
| Joint | Caulk Type | Color |
|---|---|---|
| Cabinet to painted wall | Acrylic latex | Match wall paint |
| Cabinet to tile | Silicone (color-matched) | Match grout or tile |
| Cabinet to countertop | Silicone (food-safe for kitchen) | Match countertop or clear |
| Cabinet joints (painted) | Acrylic latex | Match cabinet color |
| Exterior gaps | Weatherproof silicone | Match exterior finish |
9.4 Finishing Checklist
