Level, accessible site
Installation areas should be level, clear and accessible before the crew arrives.
Resource Center
Level Land Is Required for Proper Installation.
The building site must be level before installation. A level site helps the frame align correctly, doors operate properly, panels fit as intended, anchors perform as designed, and crews work safely.
Planning checklist
What to know before installation.
✓Confirm the full building footprint is level and square.
✓Plan drainage so water moves away from the structure.
✓Provide safe access for installation vehicles and equipment.
✓Confirm the correct foundation and anchor plan before installation.
✓Customers are responsible for site preparation unless NAC agrees otherwise in writing.
Project-specific review matters.
Engineering, permitting, availability and warranty eligibility can depend on location, size, foundation, anchors and the final ordered configuration.
