If you’re unsure of the diameter of mounting pole, frame duty or foundation size you need for your project, then you came to the right place! Our calculator will help you determine what to order based on your local site conditions. Maximum wind speeds and snow loads can be found through your local jurisdiction’s building codes or with this free website tool (https://hazards.atcouncil.org/). This calculator can be used to estimate the required foundation and/or the mount required at the install site. If any of the outputs are listed as ‘Custom’, you can change the inputs or use the ‘Go to Product’ button to fill out our project form and we will look further at the installation site and help you size the correct mount.
