Before I installed the 4 shutter tracks I laid them out to see if they were all the same size, and they were. Now that they're installed and the dome in place, the left side back end of the track is an inch higher than the right side and the roller jumps out when the shutter is open. The same dimensional difference is at the front of the tracks, but the rollers don't go down far enough to be an issue. I measured the pre-drilled holes at the back for the end of the tracks and the left side is 1" higher than the right. Were the holes drilled wrong or do the tracks have a very specific location they need to be installed to?
