The fit question
Will the selected fixture, connector, cable bend, controller, and driver fit each cabinet bay with the clearance and service access required by their own instructions?
Measure the installed envelope, not only the fixture body. A component passes only when its body, connector, cable exit, permitted orientation, documented clearance, and future access all fit. Record UNKNOWN when the selected product instructions do not establish a limit.
Name the required inputs
| Input | Required? | Unit or format | Where to obtain it |
|---|---|---|---|
| Bay width, usable depth, usable height | Required for every bay | mm or in; keep one system | Measure the actual bay at its narrowest usable points. |
| Front lip and obstructions | Required | Dimensioned note or sketch | Measure trim, hinges, shelves, plumbing, and other occupied space. |
| Fixture installed envelope | Required | W × D × H, including brackets | Selected model drawing or installation instructions. |
| Connector and cable exit | Required when present | Direction plus occupied length/depth | Selected model drawing; verify the installed connector, not a product photo. |
| Controller and driver envelope | Required when separate | W × D × H and orientation | Exact controller/driver instructions. |
| Clearance and location restrictions | Required | Exact quoted limit and source | Exact selected-product instructions. If absent, record UNKNOWN. |
| Service-access plan | Required | Removal direction and access path | Room observation plus installation instructions. |
Compare one bay at a time
- Draw the usable bay. Subtract real obstructions, not guessed allowances.
- Place the complete component chain. Show the fixture, mounting hardware, connector, cable exit, controller, and driver.
- Branch on visible or hidden placement. A hidden component still needs its permitted orientation, ventilation or clearance, and a removal path. A visible component also needs the front lip and sightline recorded.
- Check the evidence. Apply only the restrictions written for the selected model and region.
- Assign a state. PASS only when every required row is established. BLOCKED means a recorded conflict exists. VERIFY means a named document or measurement can settle the row. UNKNOWN means the needed fact is not established. NOT_APPLICABLE means the component is absent.

Evidence boundaries
The WAC Lighting BA-ACXX installation instructions show a model-family mounting and connection sequence. They are a method example, not proof of dimensions or clearances for another fixture.
The AspectLED under-cabinet light-bar installation guide treats light quantity and length, controls, connection method, power-supply location, wire runs, and voltage matching as separate system-layout inputs. Apply its product limits only to products within its stated scope.
Selected-product boundary: exact dimensions, bend space, clearance, temperature, location, and orientation limits remain UNKNOWN until the exact fixture, connector, controller, and driver instructions establish them. Do not inherit a family or example specification.
Use the completed record
This owner decides physical fit and service access only. It does not size a power supply, approve wiring, choose mounting chemistry, promise light distribution, rank products, or activate product records.
- Take supply, driver, and control questions to under-cabinet power planning.
- Take substrate and mounting preparation to the cabinet surface-prep checklist.
- Use the installation sequence guide only after fit, power, and mounting records are ready.
