I don't think I see the 1p extraction that jams the cb/ ob into the facings ad then spins both out of the pocket?
Missed opportunity... and a shot that breaks spirits.
I think you do a mock up with what you use as insulator (no slate...maybe cardboard pieces the size of the slate) before the table is installed and slap it on whn installed.
I understand folks used.styrofoam for insulation and would guess there are better options available now.
Definitely seen...
