Accordion Doors are not difficult to install. The most difficult aspect is usually measuring correctly and ordering it correctly. This commercial lunch room was a bit of a challenge because of the suspended ceiling. All the weight of an accordion door hangs from the track which is typically fastened to the ceiling.
Believe it or not, the structural ceiling in this room was approximately 8″ to 10″ above the suspended ceiling. So we employed the use of an extension ladder, anchored eye-bolts to the glue-lam structural beams above the suspended ceiling and ran steel cables down to a board that we suspended just below the finished ceiling.
This is what the accordion door looked like when the divided room was not needed by our client, and when it was all stacked up against the one wall.
