Door Section Identification
Graduated end and center hinges are always pre-attached at the top of each section (except
top section) and the graduated end hinges are stamped for identification, #1, #2, #3, and #4
(#4 only on five section doors). The stamp identifies the stacking sequence of the section.
The sequence is always determined by #1 being the bottom section to #3 or #4 being the
highest intermediate section. If the stamp on the graduated end hinge is illegible, refer to
the section side view illustration. The section side view illustration shows the graduated end
hinge profile of all sections, and can also be used to identify each section.
The
BOTTOM SECTION
can be identified by #1 graduated end hinges, the factory attached
bottom astragal, the factory attached bottom corner brackets, and by the bottom corner
bracket warning labels on each end stile.
The
LOCK SECTION
can be identified by #2 graduated end hinges.
The
INTERMEDIATE SECTION
can be identified by #3 graduated end hinges. The section
will have a warning label attached to either the right or left hand end stile.
NOTE:
#4 graduated end hinges are used on the fourth section of five section doors.
The
TOP SECTION
can be identified with no pre-installed graduated end or center hinges.
