A.G. Stacker, Inc. is located in the heart of the Shenandoah Valley of Virginia in a 100,000-plus-square-foot facility. We have been serving the corrugated industry since 1996. What started as a rigging company and machinery rebuilding business quickly turned into a new machinery manufacturing business focusing on rotary die cutter stackers. Clarence Allen’s goal is to build innovative, state of the art stackers, retrofits, and ancillary equipment and deliver customers better support than they have ever received. Over the last 21 years and hundreds of customers later, we feel we are achieving just that.

Our abilities can be your resource for an ever expanding array of manufacturing products and services. As you browse through our site, if you do not see what you are looking for, please contact us. Our history is filled with many successful, ongoing ventures sparked by a customer inquiry, or an idea, or a request to manufacture their prototype.

From inception, A.G. Stacker’s goal has been to focus on our customers and innovation. We realize without the two, we would not be in business. Our work force value their reputation for being the best at what they do. We feel our customers deserve nothing less. Our honesty, integrity, and professionalism have earned and kept A.G. Stacker customers coming back and bringing with them new customers, ideas and projects.


We consider trust to be the foundation of our relationship with our customers. We continue to invest in a highly skilled work force, top of the line equipment, safety and technology advances, and facilities to better service our customers and earn that trust. As a corrugated machine manufacturer, we understand your business. Clarence brings 10 years of experience as a plant manager at a premier sheet plant, as well as 10 years of maintenance supervisor experience. It is this background and passion for machinery combined with the knowledge of our employees that has gone into every design change and U.S. patent we have completed.

Thank you for your continued business. We look forward to building your next stacker.
