Reply To: Safe to cut an access hole in frame?

[Richard Kirshy]

I wouldn’t suggest using rivnuts, pretty sure they would hold up in that application.
I might suggest making a patch plate with a hole drilled in it and with the correct size nut welded to it.
Using a angle grinder or torch (which ever works best) Using the patch panel as a template.
Mark the area, cut it out and weld the patch panel into its place.
