At 3 m projection, the listed minimum widths are 4 m for QHA, 3.5 m for QHB and 3.55 m for QHC. All three pass a preliminary 4 m width check; the usable fixing area still needs checking.

Wall length is not the fixing width
Measure between usable fixing zones, allowing for corners, downpipes and opening windows. A nominal 4 m façade may not provide 4 m of unobstructed mounting space. Send a straight-on photograph with both ends marked.
Compare one configuration
Request the same overall width, projection, fabric and control type for all shortlisted models. Identify arm lighting separately. For a ceiling installation, QHA requires custom mounting hardware rather than assuming the wall bracket will work.
Confirm the finished position
Show where the front bar will sit relative to doors, steps and furniture. The dimensions select a candidate model; the installation drawing coordinates the actual use of the terrace.
