Acrylic wall unit with pivoting section to hide master bedroom

Here is the pivoting unit in open position. Since houzz does not have video yet, you can go to my Facebook page and watch it there. The pivoting hardware was custom made for us by a machine shop that are specialists in marine and aeronautical work. It is made up of a bottom and top bearing system with steel extension supports and 3/4" thick stainless steel pins. The bookshelf is 300lbs, but can be swiveled by a 5 year old child with no effort. There are rubber wives casters that add extra support on the end, but they are barely touching the hardwood flooring. Client is extremely happy. I had several sleepless nights wondering if this would work..
