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.

Emergency lights typically have a battery back-up that will operate the light in the event the power goes out, regardless of if there’s a generator for back-up power. Exit signs can and should also have a battery, especially if the building doesn’t have generator. Often during fire department inspections, they check that your emergency lights are operational, both with and without power. Emergency lights must be kept properly maintained to meet all federal and state requirements, so when installing new ones or updating old ones, should you just change the battery or replace the entire fixture?

There are many building codes, electrical codes, and emergency standards outlined by the Americans with Disabilities Act (ADA), National Fire Protection Association (NFPA), International Building Code (IBC), Occupational Safety and Health Administration (OSHA), state and local regulations, and others that provide lighting guidelines and requirements for commercial and similar properties. These include for interior lighting, exterior lighting, and emergency lighting.
