Please ensure this will fit across the underside of the rooflight lower frame.

PLEASE NOTE. Standard rooflights over the last 40 years in UK are known as 40 x 40cm. That is the timber frame hole in the roof is 40x40. The plastic frame is INSIDE that size. Please ensure you have a lower plastic liner that can take the strips and leave the right size for the 41 x 41 blind to stick to.

ALWAYS Measure first.

Thank you.
