Curb installations must comply with local codes and should follow the established guidelines of the National Roofing Contractors
Association. Proper unit installation requires that the roof curb be firmly and permanently attached to the roof structure.
Check for adequate fastening method prior to setting the unit on the curb.
Full perimeter roof curbs are available from the factory and are shipped unassembled. The installing contractor is responsible for
field assembly, squaring, leveling, and mounting on the roof structure. Always have a licensed HVAC contractor design and install your curb adapter.
