Hammond CWSC448GNK 48-Inch Galvanized 4x4 Wireway, No Knockouts

The CWSC448GNK is a four-foot, 48 in (1,219 mm) straight section of Type 1 lay-in screw cover wireway with a 4 in x 4 in (102 mm x 102 mm) cross-section. It is designed for electricians and OEM teams who need longer galvanized raceway sections and want to control exactly where openings go.

The section is unpainted galvanized and has no knockouts, leaving plain walls for field-punched entries or for runs that simply pass through. That avoids unused openings in a section where no side connections are needed. Wiring is laid into the channel and covered by a screw-fastened cover.

The drawing shows 4.00 in inside and 4.11 in outside dimensions, a 48.00 in overall length and typical hole diameters of 0.27 in, 0.31 in and 0.41 in. The CWSC448GNK ships in a box at 16 lbs (7.26 kg).

Compliance information includes UL File # E186830 plus REACH and RoHS compliance. In the series ordering table, the part sits in the Unpainted Galvanized, No KO, 48 in row, which spans 2.5 x 2.5 through 12 x 12. The same size with knockouts is CWSC448G.
