Function and interfaces
Lighting mounting hardware transfers the fixture load into its support and may provide an adjustable interface. Define the fixture mass, installed orientation, adjustment range, fastener arrangement and outdoor or indoor environment. Separate structural support requirements from the appearance of a visible housing.
Casting and machining review
Review ribs, bosses, slots and stops for release and local load. Specify which mating surfaces are machined or masked and how the position is locked after adjustment. Coating thickness can change slot clearance and friction. Required load, corrosion or durability tests need explicit conditions and acceptance criteria rather than a generic outdoor claim.
Requirements to define
| Interface | Review requirement |
|---|---|
| Mounting load | Fixture mass, orientation and load case |
| Adjustment | Range, stops, clearance and locking |
| Fasteners | Engagement, access and protected fits |
| Exposure | Coating system and required tests |
Example of a project decision
A coated adjustable bracket should be checked through its full movement range and locking condition. A raw-casting fit check cannot confirm the final adjustment behavior.
Information for a quotation
Send the controlled 3D model and drawing, material specification, finish, order quantities and delivery needs. Include mating parts, critical characteristics and required test records. The quotation should identify the casting, machining, finishing and inspection scope, together with any open decisions. Request a drawing review.
