The inner door hinges (NCWT0122) are bolted to the inner door frame weldment. (See detail B in

The 2 ring door requires eight (8) total latch bar holders (WD-6234) assembled to the inner door frame
weldment. Washers will be used to adjust the distance between the frame and the latch bar holder for the
best fit of the inner doors. Use 1/2" washers (S-2120) and 1/2" x 1-1/2" bolt (S-3728) to secure the latch
bar holders (WD-6234). (See detail A in

inner door weldment using 5/16" x 1-1/2" bolts (S-2741), washer (S-845) and flange nut (S-3611). The
bearing pins should be attached at the eight (8) slots in the inner face of the weldment as shown in
