This is the HD 8 Column Full Height Double deep rack from Wine Racks America and measures 67 1/8" high x 29 1/2" wide x 24 1/2" deep. Details are here: https://wineracksamerica.com/product/8col-fh-dd/.
The rack cost $900 new, any offers?
I no longer need this as I moved my wine to a facility that built racks for me.
Thanks for looking.
