Can you please provide the pole mounting flange hole center-center specs so I can get my anchor bolts installed in the concrete ahead of physically having the unit? Concrete is going in this week and didn’t realize I wouldn’t be able to find the specs

Depends on the model. Use our installation resources here ... scroll down to "Other Resources" and then click "Pier Kit Hole Pattern Diagrams." Alternatively, we can overnight a pier kit to you via UPS. Please call in for this service if you're interested 888-600-8545.
