Steel framed doors

Expensive door jams have screw holes for tapcoms to install into concrete foundation or

wood framed jams. Cheap door, you have to morter the jam in place. I drill a 1/2in

hole through the rise plate(frame stop ) then drill hole size of screw through the outer

plate that is against the foundation or jam. This way you do not see the screws that

are holding the frame.
