We found this difficult to put together. The tiny predrilled holes in the wood did not line up properly and the screws were too short to hold it together. We had to get longer screws from our workshop to use. Also the feet aren’t really sufficient for all rulers and the groves for the rulers could be deeper and line up a bit better.
Thank you for letting us know about this issue. Please do contact our Customer Service Team, they will be happy to look into this further.
