Glass Master Spacing Setup for Air Duct Boards

Proper adjustment of grooving machines is essential to producing quality air duct board sections at the lowest possible contractor cost. Several models have been produced by Glass Master since machines were first introduced into the air handling market. However, the basic design concept remains the same today as when first produced. Regardless of the model or year of production, the basic mechanical principles of adjustment discussed in this video still apply. The E-215 machine is the base upon which all other models are manufactured. E-215 machines in use far outnumber all other models in use at this time. This video focuses on adjustment of spacers to make an 11"" X 11"" Duct.
