For a 3 m overall width, the supplied matrices list up to 2 m projection for QHA, 2.5 m for QHB and 2 m for QHC. These are table-based screening results, subject to order confirmation.
Measure the full mounting zone
A 3 m window opening does not establish a 3 m mounting width. Record walls, downpipes and doors on both sides, and ask whether the quoted width means overall cassette width or fabric width.
Do not round a threshold down
QHC lists 3.05 m minimum width for 2.5 m projection. A 3 m space is 50 mm short of that threshold. Request another configuration rather than treating the difference as installation tolerance.
Check the shaded area separately
Projection describes the product dimension, not guaranteed shade at every hour. Mark the dining area and review sun direction before deciding whether a shorter projection meets the intended use.
