I designed this so I could use my Matchbox/Hotwheels display shelfs on Mulitboard. You have to use the ones I designed for normal pegboards and not the ones for Skadis pegboards. Here is link to those. Just use this hook adapter instead of the one in the link.

The author remixed this model.
Removed the back Skadis prongs with prongs to be used on Multiboard.
