Requirements:

The FLEX MAX Door handle is suitable for following door dimensions:

• Door thickness: 30mm~50mm (Corresponding screws for 30-50mm | 35-40mm | 40-50mm door widths)
• We recommend a minimum distance between the centre of your door lock and the door frame (backset) of 40 mm, so that the door fitting does not touch the frame.
• You need two 8mm holes to the left and right of the square, 38mm apart.

Instructions for measuring the required dimensions can be found here.
