This is model 8539SC G 44v81. If it’s listed here then it’s available so no need to ask . This is Brand new in the box and never used. I am pricing this very low for a quick turnaround and sale. These typically go for $2500 -$3000. Located in Worcester near lake ave and hamilton and available to pick up Daily from 10 AM until 9 PM. You’ll never find this for this price anywhere else .You could make money on this if you know an electrician that does big commercial buildings. This is not for a residential house.
