12. TRACK ASSEMBLY-Separate the track bundles. The two curved pieces are the left and right horizontals, the two straight ones are identical and make up the left and right vertical assemblies.
NOTE: -While assembling, keep all nuts and bolts loose.
To make the vertical assembly attach the #5 track bracket to the lowest slotted hole set and the #6 track bracket to the middle slotted hole set. For now the upper slotted hole set is ignored. Next, attach the flag bracket through it's lower slot to the TOP most two holes in the track. The flanges of these three brackets should extend outward away from the door and not inward behind the track. The inside cup of the track should open inward toward the door. Assemble the vertical for the other side of the door so that when finished the two are mirror images of each other.
Attach the horizontals to the verticals. Connect the horizontal to the flag bracket with one 3/8" bolt. Align the horizontal and vertical sections at the flag bracket and attach the horizontal to the upper slot in the flag bracket. When tight the horizontal and vertical sections should be a square. Next, attach the end bearing plate to the horizontal track so when attached the flange is even with the flag bracket and pointing away from the door. Tighten accordingly.
Repeat for other side. When finished they should be mirror images of one another.
You are now ready to stack the door
13. STACKING THE DOOR-Center the bottom section in the garage opening and hold the section in place with nails driven into the jamb and bent over against the section. Next, using a level, shim the panel at one end until dead level. Place each section in the opening on top of the previous section checking and adjusting for level each time. Finally, affix hinges and rollers to each succeeding section.
You should now have the complete door in the opening with all rollers in place. It should look exactly like this.
You are now ready to track the door
NOTE:-Before tracking the door we recommend you get another person to help you as this can be very difficult and possibly dangerous if done incorrectly.
14. TRACKING THE DOOR-First, straighten all rollers and drape the cables up behind them to get the cable out of the way. Work the right track assembly around the rollers. Using 5/16" x 1-1/2" lags, mark, pre-drill, and attach the track brackets to the wall. The track should be vertical with 1/2" clearance between it's inner edge and the door all the way up. With the track secured, lag down the flap bracket with three lags, keeping it vertical. Pull out the nails holding that side of the door up and move this side of the track forward or backward (remembering the adjustable slotted holes on the track brackets) until you have about 1/2" clearance between the face of the door and the jamb. Tighten all the track bolts.
Repeat this for the left side of the door.
You are now ready to mount the springs
15. SPRING MOUNTING-Place the stepladder at the center of the door. Center the springs on the shaft assembly, making sure to set at least one set screw so that it won't slide. Standing at the base of the ladder, place one end of the shaft on the horizontal track at the end bearing plate and climb the ladder. Place the end of the shaft into the end bearing plate, sliding it until the other end of the shaft can be set into its bearing.
NOTE:-If there is not enough clearance you may have to cut a few (no more than 5) inches off the shaft.
With the shaft entered (equal amounts of shaft left out of the end bearings), raise the springs until the shaft is level and mark the holes of the center plates flange onto the wood center pad.
NOTE:-If you plan to install a garage door opener in the future, offset the center flange so the base of the opener can be mounted.
Pre-drill two 1/4" holes. Fasten the center bearing plate to the spring pad with 5/16" x 2-1/2" lags.
