Hammond CWSC424G 24-Inch Galvanized 4x4 Wireway with Knockouts

The CWSC424G is a 24 in (610 mm) straight section of Type 1 lay-in screw cover wireway in an unpainted galvanized finish, with a 4 in x 4 in (102 mm x 102 mm) cross-section. It is intended for electricians and OEM builders who want an enclosed indoor wiring channel and prefer galvanized over painted steel.

The section includes knockouts; Detail Z on the drawing shows diameters of 0.83 in and 0.88 in. Because the wireway is lay-in, conductors are placed directly into the open channel and the screw cover is attached afterwards, simplifying both first installation and later additions.

Per the manufacturer drawing, the CWSC424G measures 4.00 in inside and 4.11 in outside, with a 24.00 in overall length and typical hole diameters of 0.27 in, 0.31 in and 0.41 in. It is shipped in a box with a weight of 7 lbs (3.18 kg).

The part references UL File # E186830 and is listed as REACH and RoHS compliant. It sits in the 24 in w/KO row of the Unpainted Galvanized table, alongside 2.5 x 2.5, 6 x 6, 8 x 8 and 12 x 12 galvanized sections. The no-knockout galvanized version is CWSC424GNK; the painted gray version is CWSC424.
