Start with the width and projection combination, then compare mounting and optional equipment. QHA, QHB and QHC have different size matrices; the largest advertised dimension alone is not enough to select a model.
Compare usable combinations
At 3 m projection, listed minimum widths are 4 m for QHA, 3.5 m for QHB and 3.55 m for QHC. A narrow façade can therefore change the shortlist before finishes are considered.
Separate standard and custom mounting
The QHA brochure marks ceiling mounting as custom. Do not assume every illustrated bracket is included. Ask each quotation to identify the mounting surface, bracket version and supplied fasteners.
Compare the same specification
Use identical width, projection, fabric reference and control requirements in all three enquiries. A lower price with a different motor, fewer mounting parts or excluded lighting is not a like-for-like offer.
