Hmmm I’m not familiar with the lil mynx pole its self but… don’t use a toggle its not safe. S There is usually 2 types of metal used in that type of beam. Once is cast iron the other is just a folded piece of metal and wouldn’t be sturdy enough to hold your pole. I hope you get it work out. https://www.studioveena.com/img/smilies/icon_flower.gif
