Yes, the problem is the MDF. However it's 1" thick, so if I could find shelf pins that go in 3/4" and if anything were thicker, that would make a big difference I think.
A customer is asking. I'm just doing some research to help them, they have someone else to do this kind of work for them.
I will definitely recommend drilling another hole on each side of the shelves (they are probably 28" x 24" or something like that.) With 3 holes on each side and a couple along the back edge, that should do it. I think those grommets might be the way to go.
