Hi all I hope this is not too much of a stupid question..! Ive got some 35mm thick doors that are due to be installed shortly. Noticed many of the “lever on latch” handles on the Screwfix website state “suitable door thickness” of 44mm. Is this the maximum width of the door (ie. is this suitable for my 35mm doors)? As I can’t seem to find anything at Screwfix that isn’t 44mm!
