Building an Adjustable Tension Board

I really wanted to add a systems board to my business facility at Mountain Movement, but since I only have 11 foot ceilings I was compelled to think outside the box. We made an adjustable board not just at the angle of the wall, but also weather or not to utilize the last 3 rows of the board. At less than 35 degrees my space didn’t work for a full board, but it did have enough space for a 1-15 set up. We put the last 3 rows on a hinge so we can fold it back to use the board at 20-35 degrees. Then when it reaches 40 or more degrees we flip the top up and have full board access. This thing is pretty solid and I haven’t seen anyone else use the board in this way. I’d be interested in what you all think!
