The CWST496NK is a 96 in (2,438 mm) hinge cover straight section for 4 x 4 in Type 1 lay-in wireway, built without knockouts. Its length is covered by two hinged covers of 47.94 in each, and it suits long indoor runs in machine building and general plant wiring projects where cable is laid in rather than pulled through.
The body and cover are formed from 16 or 14 gauge steel and finished in ANSI 61 gray. CW Series hinge covers are hinged on 24 in centers, and this section carries two hinged covers of 47.94 in each. The interior is unobstructed to speed up laying of cables, and because this is a no-knockout (NK) section the walls are left plain. A version with knockouts is listed as CWST496.
Nominal size is 4 in x 4 in x 96 in (102 mm x 102 mm x 2,438 mm). The drawing shows a 4 in x 4 in inside cross-section, a cover width of 4.36 in and outside body dimensions of 4.11 in x 4.06 in. Shipping weight is 26 lbs (11.79 kg), and the part ships in a box.
Construction is designed to ensure electrical continuity and to permit fast, easy indoor installation of multiple wireway runs. Optional hanger brackets allow vertical or horizontal mounting: the wall type bracket for this size is CWHW4 and the ceiling type is CWHD4. Effective May 4, 2026, joiners are no longer included with straight sections, so order the 4 x 4 joiner CWJO4 separately as required.
The CWST496NK is covered by the series standards UL-870 Type 1 and cUL Type 1, and complies with IEC 60529, IP20. It is listed under UL File E186830 and is RoHS and REACH compliant.
