ARK DESIGN Scratch Resistant Tempered Frosted Glass Bi-Fold Doors, White, 60" x 80", 51 lbs

I am a mechanical engineer and woodworker. I build my own doors %26 frames from scratch, so I have a massive amount of experience with doors. This door were the most difficult to assemble and install I have ever come across. Instead or selling a dedicated left door and a dedicated right door, they manufacture a generic door. It saves them money but cost you much more time in assembly. I spent two hours assembling the door and another hour installing (with a helper). Many of the components look alike with just very slight differences in length. You wont know that you used the wrong piece until you try to hang the door. You need to be able to measure and install accurately to 1/16 of an inch. There is some adjustment opportunity once installed using the set screws. The door is heavy and requires two people to lift and hang it. The manufacturer uses 3m double sided tape on the trim pieces. I would have preferred a mechanical fastener.
