I have a 2 year old Glass Master duct board machine for sale. The machine will cut up to 2 inch duct board. Comes with a set of 1 and 1.5 inch blades. Economy has forced me to down size. I have only been doing service work for the last 6 months and the machine hasn't been used at all during that time. I am asking $6,500 but will consider any reasonable offer. Pictures available upon request.
