Hammond CWSC460GNK 60-Inch Galvanized 4x4 Wireway, No Knockouts

The CWSC460GNK is a five-foot, 60 in (1,524 mm) 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 intended for long, straight indoor runs where the installer wants galvanized raceway and full control over entry locations.

The unpainted galvanized walls have no knockouts. That keeps the section closed along its full length unless you punch it, which is useful for pass-through runs or layouts where entries must line up with specific equipment. Wires are laid into the open channel and enclosed by the screw cover.

Per the manufacturer drawing, the section is 4.00 in inside and 4.11 in outside, 60.00 in overall, with typical hole diameters of 0.27 in, 0.31 in and 0.41 in. Shipping weight is 18 lbs (8.16 kg), and the part comes in a box.

The CWSC460GNK carries UL File # E186830 and is listed as REACH and RoHS compliant. It belongs to the Unpainted Galvanized, No KO, 60 in row of the ordering table, alongside 2.5 x 2.5, 6 x 6, 8 x 8, 10 x 10 and 12 x 12 sections. The knockout version of this size is CWSC460G.
