Read
Understand which surfaces and clearances define the product.
Measure with confidence
The guide is part of the product.
Read the right guide before entering a size. Magnetic, retractable and outdoor systems do not share one measuring rule, and the advanced DIY products need a site assessment as well as dimensions.
Workshop rule 01
Resolve the opening first.
Packing, angles, boxing and final surfaces can change the size. Final measurement comes after those decisions.
