The CS443 is the smallest box in the CS range: a 4 x 4 x 3 in Type 1 screw-cover junction box with no knockouts, sized for a handful of splices or a single device pull point. Designed for general purpose indoor commercial use as a junction, pull or switch box, it suits electricians, contractors and facilities teams working on indoor wiring.
The CS443 is formed and spot welded from 16 gauge steel (the series uses 16 gauge for sizes up to 30 x 24 in). 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. The box has no knockouts.
Nominal size is 4 in x 4 in x 3 in (102 mm x 102 mm x 76 mm). The part drawing shows an overall depth of 3.06 in with the cover fitted, and through holes in the back allow wall mounting. Shipping weight is 2 lbs (0.91 kg), and it is packaged in a bag.
The CS series is UL-50 Type 1 (UL File E65324) and CSA Type 1 (CSA Cert. LR21001), and complies with NEMA Type 1 and IEC 60529, IP20. The part is listed as REACH and RoHS compliant. Series accessories include flush covers, Type 1 extenders and CS perforated panels.
