The QHA introduction says 3 m projection, while its selection matrix includes 3.5 m at widths of 4.5 m and above. Treat 3.5 m as a configuration to confirm, not an unconditional specification.
Identify both source pages
Send pages 4 and 5 with the enquiry and mark the required width and projection. This makes the question specific and prevents a reply that simply repeats the headline range.
Get one approved configuration
Ask the supplier to state the available arm set, bracket configuration and applicable revision for the proposed size. Keep that answer with the approved drawing before paying for a custom unit.
Use alternatives without assuming equivalence
If QHA availability remains unclear, compare QHB and QHC using their own tables. Changing model can change minimum width and mounting details, so an alternative needs a fresh drawing and quotation.
