Bolt Circle Calculator

Knowing the pole base anchor bolt configuration is important when it comes to determining the bolt circle calculation for light poles. The majority of light poles that we see are square with anchor bolts in the corners. At times, there is an existing pole in place which makes it difficult to measure the corner to corner diagonal. Our calculator will help calculate the bolt circle for square 4-bolt patterns where the only measurement needed is the space between bolts.

Enter the information below to estimate your bolt circle calculation.

In April, the Department of Energy finalized two rules requiring manufactures to sell energy-efficient lightbulbs. This means older, inefficient lightbulbs that don’t meet the new standards can no longer be manufactured and sold. The primary purposes for these rules are to drive down electricity use, save consumers money, and decrease greenhouse gas emissions.

It’s estimated that schools spend billions of dollars annually on energy, and it’s often the second-highest operating expenditure (following personnel costs). Each year, these expenses continue to increase while budgets often decrease, leading educators to look for ways to save money throughout the year. One way is by making some lighting updates that are more energy efficient, therefore saving money on energy bills. LED uses up to 75% less energy than conventional lighting systems, which keeps dollars in your budget for other important things.
