This shelf was a chore to build. If your like me I work out of my Garage. It is 12.6 feet long and 8.5 feet tall. Made out of 3/4 commercial grade Oak plywood. Each shelf unit built by itself and then put together. It was built to hold file boxes at a law office. remember I build a lot of stuff out of can’t find anywhere else. And this is one filled my shop while building it.  We stained each shelf by itself and then put it together in the drive way to do all the finishing touches. There is six bolts holding these sections together and it is attached to the wall in 4 places.

I laid the pieces down and used my Ryobi router to rout all the slots to hold the shelves.
