The CS16168 is a square NEMA Type 1 mild steel junction box measuring 16 in high by 16 in wide by 8 in deep (406 x 406 x 203 mm). It belongs to the CS series of screw-cover boxes supplied without knockouts, and is designed for general purpose indoor commercial use as a junction, pull or switch box. Electricians, electrical contractors and facilities teams can use it wherever wiring needs an enclosed, accessible splice or pull point inside a building.

The body is formed and spot welded from steel; the series sheet specifies 16 gauge steel for sizes up to 30" x 24", which covers this 16" x 16" part. A flat steel cover is fastened with plated steel screws, and keyhole slots let the cover be lifted off without removing the screws entirely. The enclosure and cover are finished in ANSI 61 gray powder coating, and a grounding location is embossed in the body.

Because the CS16168 has no knockouts, conductor entries can be placed exactly where the installation calls for them. Its 8 in depth gives generous interior volume for large conductor runs and multiple splices. The manufacturer drawing shows an overall depth of 8.06 in with the cover fitted, and the box mounts to a wall through holes in the back.

The CS series is listed to UL-50 Type 1 (UL File E65324) and CSA Type 1 (CSA Certificate LR21001), and complies with NEMA Type 1 and IEC 60529 IP20. This part is REACH and RoHS compliant, ships in a box and has a shipping weight of 18 lbs (8.16 kg).
