What Tools do You Need to Build UL508A Industrial Control Panels? 

I talk a little about leaving the fingers in on intersections to help that in this video. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zz5xEB4KuaU.htmlsi=QF-BkIzuEZS8RFLQ There are also some claws that you can install along with the wire duct but I have never used them. I should have mentioned it in the video but for managing wires during the build, I cut small pieces of cardboard and stick them between the fingers to hold the wires down.
