PART-SPECIFIC BUYING QUESTIONS — original editorial guidance
First decision: Is the internal opening functional, or is the outside envelope the controlling assembly interface?
Interfaces: Dimension the outside shape, internal opening and mating components. Include insertion depth or end engagement where the tube joins another part.
Finished-part scope: List end cuts, slots and mounting holes. Identify surfaces that require protection in packing and whether a mill or black-anodized condition is required.
Sample and acceptance: Specify the relevant tube-fit checks and end condition. For anodized parts, agree the appearance reference and faces where contact marks are acceptable.
