Product Specification Worksheets


Your basic application data

Our expert applications engineers are standing by to assist you with your tension equipment selection and  specifying of sizing and options. Aside from the basic application information that you can complete and submit directly from the Basic Application Information form, we encourage you to let our sales and application engineers do the work for you. You can reach them at the factory in Rochester, NH by phone at +(603) 332-6150 or by email at

The more you can tell us about your web process and your machine configuration the better, but we need most of this Basic Application Information to get started.

If you would prefer to start from scratch, because you're not sure where your application would use tension control equipment, you can just submit this simple form for a free application analysis from a qualified DFE Sales Representative. We discuss your application in detail with you to determine what tension control solution, if any, might be appropriate for your budget.

Product Specification Worksheets

These Product Specification worksheets are some of the tools that our sales team uses to generate an accurately configured product and a price quotation. They are somewhat complicated. We recognize that, and we welcome your input for improving them. We are sharing them here as a configurator reference for you.

If you decide to use one or more of these worksheets for DFE product selection, please do not hesitate to contact your local DFE Sales representative or one of our factory-certified inhouse Application Engineers to help answer your questions about the form. We also recommend that you have the DFE data sheets handy for the products you may be interested in configuring.
