I have fitted the frame for my new French Doors. Everything is square and doors fit perfectly but the top of the frame droops when doors are opened.
I can't see any fixing holes to drill through??Am I missing something and which drillbit is the best for going through Upvc and steel lintel??

you have to toe and heel the doors

the general trade solution to this would be to prop the frame a correct height and inject expanding foam into surrounding space/cavity.sets hard and sticks to everything.Id still like to put a fixing through though.best drill would be hss or better for drilling steel.
