i can post photos/video of my rack's heat tape when i'm home. basically there's a hole cut out on the edge of each self so the heat tape can be fed through to the shelves below. my heat tape is weaved in an "S" shape through my three shelves.
That would be awesome tttaylorrr! Thanks for all your help.
