I will shortly be installing an FD30 Flush Fire Resistant Smooth Veneer Door 78" x 30" x 1¾, but before I start I have a question to which I would be very grateful for an answer.
The Question is regarding the hinge positions
In the installation directions booklet it states
“Top hinge positioned 150mm from the top of the door
Bottom hinge positioned 225-250 from the base of the door
Middle hinge positioned centrallyâ€
