Mileage will vary, the peg board I was using has larger holes for example.

Nice and simple holder to use for mounting framed items onto a 1-inch pegboard. I used two holders for my mounting purposes - one on the bottom and one inverted on the top.

I've included a STEP file to allow you to adapt this to your needs. I tried to model it in an easy-to-use way, but let me know if you run into any issues and I can look into revisions.
