Choose between two new-work box formats in one product page: the SN18X 18 cu. in. 1-gang nail-on box and the SN20XC 20.3 cu. in. round nail-on ceiling box. Select the exact box style and package count before ordering.
Key Features
- Two distinct formats: SN18X rectangular 1-gang and SN20XC round ceiling-box styles.
- Both series are intended for new-work installation and include attached mounting nails as shown.
- Package choices are tied to exact SKU images: SN18X in 1, 3, or 10 packs; SN20XC in 1, 3, or 12 packs.
- Use the model, shape, capacity, and pack table below to avoid mixing the two box families.
