Hammond CWSC472GNK 72-Inch Galvanized 4x4 Wireway, No Knockouts

The CWSC472GNK is a six-foot, 72 in (1,829 mm) straight section of CWSC Series Type 1 lay-in screw cover wireway with a 4 in x 4 in (102 mm x 102 mm) cross-section. It is built for long indoor runs where an installer wants galvanized raceway, fewer joints and walls free of pre-formed openings.

The finish is unpainted galvanized and the walls have no knockouts, so entries are punched only where they are needed - or not at all on a straight pass-through. Conductors are laid into the open channel, and the screw cover is fastened on to enclose the run, avoiding long wire pulls through the section.

The drawing lists a 4.00 in inside dimension, a 4.11 in outside dimension and a 72.00 in overall length, together with typical hole diameters of 0.27 in, 0.31 in and 0.41 in. The part ships in a box at 22 lbs (9.98 kg).

The CWSC472GNK is listed under UL File # E186830 and is REACH and RoHS compliant. Its row in the ordering table - Unpainted Galvanized, No KO, 72 in - also contains 6 x 6, 8 x 8, 10 x 10 and 12 x 12 sections for larger wire fills. The galvanized 4 x 4 x 72 in version with knockouts is CWSC472G.
