Hammond CS202010 20x20x10 in Type 1 Screw Cover Junction Box

The CS202010 is a square NEMA Type 1 mild steel junction box measuring 20 in high by 20 in wide by 10 in deep (508 x 508 x 254 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 20" x 20" 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 CS202010 has no knockouts, conductor entries can be placed exactly where the installation calls for them. Its 10 in depth provides a deep interior for heavy conductor bundles and larger pull or junction assemblies. The manufacturer drawing shows an overall depth of 10.06 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 35 lbs (15.88 kg).
