Iberville 54151K Octagonal Ceiling Box
The Iberville 54151K Octagonal Ceiling Box is positioned as a cost-conscious, code-ready octagonal metal box optimized for general ceiling fixture and junction use; it balances stamped-steel durability with a competitive price that undercuts some premium brands while still accepting standard fixture screws and conduit. Compared with the other boxes on this list, Iberville offers a strong value proposition for contractors who need a metal octagonal solution without the premium cost of market-leader octagonal models, though it does not carry the specialized fan-mount features of Arlington or the retrofit convenience of Hubbell Raco.

Carlon B520A-UPC Round Ceiling Box
The Carlon B520A-UPC Round Ceiling Box is a non-metallic, corrosion-resistant option that excels for lightweight fixtures, damp locations, and jobs where cost and ease of handling matter most; its plastic construction makes it affordable and impervious to rust, a financial advantage over metal boxes in specific environments. While Carlon’s round design is less suitable for heavy ceiling fans than Arlington’s steel fan box or for high-load fixtures that prefer metal octagonal boxes like the Iberville or Thomas & Betts units, it remains a market-leading choice for economical residential ceiling lighting and simple retrofits.
Lightweight plastic — no buzz
Moisture-friendly — mold shy

Arlington FBS415 Steel Fan Box
The Arlington FBS415 Steel Fan Box occupies the heavy-duty niche as a purpose-built fan-mount ceiling box, delivering superior load capacity, integrated hanger features, and robust steel construction needed for ceiling fans and heavier fixtures; it justifies a higher price with higher safety margins and simplified fan installations. Compared to the round or octagonal general-purpose boxes here, Arlington’s product is the technical leader for fan support—outclassing Carlon and many octagonal boxes on load rating—though it is a more specialized and premium-priced choice than the value-oriented Iberville.
