Despite clear code requirements for positive attachment, the building industry has widely adopted methods that fail to meet the intent of the codes. Common practices such as using screws or slack wires do not ensure that the lighting fixture and ceiling grid behave as one unified system under seismic forces.
This misinterpretation of code intent led to the ICC publishing AC184 to establish clear, testable criteria for what constitutes true positive attachment.
The SFC is the solution — it's the first product to meet AC184 criteria without requiring additional slack wires.
