Graduated End Hinge Schedule
Door Height Section Type Graduated End Hinge Number
3 Section High Door Bottom #2
4 Section High Door #1
NOTE: Center hinge(s) use #1 graduated end hinges at each pre-drilled or vertical stile loca-
tion. The pre-drilled locations are located at the top rails on the inside of the section surface.
NOTE: Measure the height of the long strut(s) to determine if you have 2” or 3”.
NOTE: Some struts also may or may not have holes in them. If they don’t, then prior to
installing the strut and hinge to the section surface, you may have to drill a 3/16” hole for the
appropriate fastener on one or both sides of the strut legs.
Using the appropriate graduated end hinges for the ends and depending on the width of your
door, enough center hinge(s) for each pre-drilled hole location(s). Starting at the upper left
hand corner of the bottom section. Position the lower hinge leaf of the appropriate graduated
end hinge onto the upper corner of the bottom section. Align the slots of the lower hinge leaf
with the pre-drilled holes in the bottom section.
NOTE: If you have strut clips, ensure the strut clip is positioned on the hinge, as shown.
FOR GRADUATED END HINGES:
IF YOU HAVE 2” LONG STRUTS: Lay the leg of the long strut over the bottom hole of the
lower hinge leaf and the bottom section. Center the long strut from side to side. Attach the
upper slot of the graduated end hinge to the bottom section using (1) 1/4” - 20 x 2-1/4”
carriage bolt and (1) 1/4” - 20 flange hex nut. Next attach the bottom hole of the graduated
end hinge to the upper leg of the strut to the bottom section using (1) 1/4” - 20 x 2-1/4”
carriage bolt and (1) 1/4” - 20 flange hex nut. Next secure the bottom leg of the strut to the
bottom section using (1) 1/4” - 20 x 2-1/4” carriage bolt and (1) 1/4” - 20 flange hex nut.
Repeat for other side.
IF YOU HAVE 3” LONG STRUTS: Lay a long strut over the lower hinge leaf and over the top
rail of the bottom section. Center the long strut from side to side. Attach the upper slot of the
graduated end hinge, (1) strut clip to the upper leg of the strut to the bottom section using (1)
1/4” - 20 x 2-1/4” carriage bolt and (1) 1/4” - 20 flange hex nut. Next secure the bottom leg
of the strut with the hole of the graduated end hinge to the bottom section using (1) 1/4” -
20 x 2-1/4” carriage bolt and (1) 1/4” - 20 flange hex nut. Repeat for other side.
IF YOU HAVE DOUBLE GRADUATED END HINGES: Position the second graduated end
hinge next to the first (single) graduated end hinge. Using the second graduated end hinge as
a template, drill pilot holes, 1” deep into the bottom section using a 1/8” drill bit.
IMPORTANT: BE EXTREMELY CAREFUL NOT TO DRILL THRU THE SECTION. ONLY DRILL 1”
DEEP.
Secure the strut and the graduated end hinge to the bottom section using (2) 1/4” - 14 x 1”
lag screws. Repeat for other side.
FOR CENTER HINGES: Align the slots of the lower hinge leaf with the pre-drilled holes at
each center stile, located at the top rail of the bottom section. Using the center hinge as a
template, drill pilot holes, 1” deep into the bottom section with a 1/8” drill bit (if needed).
IMPORTANT: BE EXTREMELY CAREFUL NOT TO DRILL THRU THE SECTION. ONLY DRILL 1”
DEEP.
IF YOU HAVE 2” LONG STRUTS: Attach the upper slot of the center hinge using a 1/4” - 14
x 1” lag screw. Secure the leg of the strut to the hole of the center hinge using a 1/4” - 14 x
1” lag screw. Secure the other leg of the strut to the section using a 1/4” - 14 x 1” lag screw.
Repeat for other center hinge(s).
IF YOU HAVE 3” LONG STRUTS: Attach the upper leg of the strut to the upper slot of the
center hinge using (1) strut clip and a 1/4” - 14 x 1” lag screw. Secure the lower leg of the
strut to the hole of the center hinge using a 1/4” - 14 x 1” lag screw. Repeat for other center
hinge(s).
NOTE: If you don’t have half center hinges, then skip this part of the step. Refer to Package
Contents / Breakdown Of Parts, to determine if you have half center hinges.
Using a tape measure, position the half center hinges equally spaced in between the center
hinges and the graduated end hinges. Position the holes of the lower hinge leaf at the top rail
of the bottom section. Using the half center hinge as a template, drill pilot holes, 1” deep into
the bottom section with a 1/8” drill bit (if needed).
IMPORTANT: BE EXTREMELY CAREFUL NOT TO DRILL THRU THE SECTION. ONLY DRILL 1”
DEEP.
Attach the lower hinge leaf of the center hinge to the bottom section using (2) 1/4” - 14 x 1”
lag screws. Repeat for other half center hinge(s).
If you have single graduated end hinges, insert a short stem track roller / short stem tandem
track roller (if included) into the hinge tube on each side.
If you have double graduated end hinges, insert a long stem track roller / short stem tandem
track roller (if included) into the hinge tubes on each side.
IMPORTANT: WHEN PLACING TRACK ROLLERS / TANDEM TRACK ROLLER (IF INCLUDED)
INTO GRADUATED END HINGES NUMBER 2 AND HIGHER, THE TRACK ROLLER / TANDEM
TRACK ROLLER (IF INCLUDED) GOES INTO TUBE FURTHEST AWAY FROM SECTION.

NOTE: Refer to door section identification, located in the pre-installation section of this
manual to determine what size section you need to use as your intermediate I (second) and if
applicable intermediate II (third) section. Measure your section to make sure it is the correct
height as indicated on the chart.
NOTE: Refer to the Graduated End Hinge Schedule below, to determine the appropriate
hinges for your bottom section.
