patching holes in panels

[iwire]

BUT Pierre this goes hand in hand with the dumbification of our trade. Common sense and experience SHOULD go a long way, but it has no bearing anymore. I guran-fricking-tee you that a 1900 plate WITH TAPPETS (I use 1/4-20s) equals or exceeds reducing washers, the flimsy sometime impossible to seat junk.

I can not help but agree here, it makes no sense at all to just assume that box cover of much thicker material is not as good or better then flimsy reducing washers only because it is untested for this use.
