Screws provided for aluminium side rails are unnecessarily large gauge so used the smaller five star screws from the previous Velux Blind - unlike the previous blind the new unit does not grip the side brackets tightly when fitting so 3 hands required to fit. Packaging offers no impact protection for side rails.

Thank you for your detailed feedback. We're sorry to hear that aspects of the installation did not meet your expectations. We're also sorry to hear that you felt the packaging did not provide sufficient impact protection for the side rails. Feedback like yours is valuable, as it helps us identify areas where product design and packaging can be improved.
