Tools Required: None |

NOTE: The bottom section can be identified by the smallest graduated edge hinge of the factory installed graduated edge hinges, see Door Section Identification.
WarningARNING
Failure to ensure tight fit of cable loop over milford pin could result in counterbalance lift cable coming off the pin, allowing the door to fall, possibly resulting in severe or fatal injury.
NOTE: Cable drum assemblies are marked right and left hand.
Uncoil the counterbalance lift cables from the cable drum assemblies. Starting on the left hand side, place the left hand cable loop on the left hand milford pin of the bottom corner bracket and the right hand cable loop on the right hand milford pin of the factory attached bottom corner bracket. Insert a short stem track roller into the factory attached bottom corner bracket and another into the #1 graduated end hinge at the top of the bottom section. Repeat for other side.
NOTE: Check to ensure cable loops fits tightly over the milford pins.
NOTE: Larger doors will use long stem track rollers with double graduated end hinges. They will also use short stem track rollers for the factory attached bottom corner brackets.
NOTE: Verify bottom weather seal is aligned with bottom section. If there is more than 1/2” excess weather seal on either side, trim weather seal even with bottom section.
6 | Bottom Section | |
Tools Required: Level, Wooden shims (if necessary) | ||
|
Center the bottom section in the door opening. Level the section using wooden shims (if necessary) under the bottom section. When the bottom section is leveled, temporarily hold it in place by driving a nail into the jamb and bending it over the edge of the bottom section on both sides.

Level, Step ladder |
NOTE: Depending on your door, you may have Quick Install Flag Angles, Fully Adjustable Flag Angles or you may have Riveted Vertical Track Assemblies. Refer to Package Contents / Parts Breakdown, to determine which Flag Angles / Vertical Track Assemblies you have.
IMPORTANT: If your door is to be installed prior to a finishing construction of the building’s floor, the vertical tracks and the door bottom section assembly should be installed such that when the floor is constructed, no door or track parts are trapped in the floor construction.
IMPORTANT: the tops of the vertical track assemblies must be level from side to side. If the bottom section was shimmed to level it, the vertical track as- sembly on the shimmed side must be raised the height of the shim.
Starting on the left hand side of the bottom section, remove the nail. Position the left hand vertical track assembly over the track rollers of the bottom section. Make sure the coun- terbalance lift cable is located between the track rollers and the door jamb. Drill 3/16” pilot holes into the door jamb for the lag screws.
For Quick Install Flag Angles, Fully Adjustable Flag Angles or Riveted Vertical Track Assemblies: Loosely fasten jamb brackets and flag angle to the jamb using 5/16” x
