STEP 2: MOUNTING PLATES
A If the door will be installed to steel jambs, mounting
plates for the door mounting plates are required and
may be welded or bolted to the jambs.
B Top of mounting plates should be located approximately
10 inches above the top of the door opening. The inside
edge of mounting plate should be 1 1/2” from the inside
of the door jamb. (Note: direction of arrows
on mounting plates.) This is the most important
step; mounting plates MUST be level to each other;
checking via laser or water level is recommended,
do not go by relationship to door header; door header
may not be level.
