These Verticals Tell a Story

I learned some interesting things being called out to troubleshoot this sliding door. In this photo you can see the space between vertical interlocks is not uniform on the 12' tall panels. Obviously they were slightly out of level, but as I rolled panels across the opening the gaps changed and I realized the track was badly shimmed and flexing under the weight of the panels.

This was a quarter million dollar window package I lost in 2017 and in 2018 I got to see why the other company was cheaper. Every time you go with the lowest bid, you are getting what you pay for.
