Hammond CWST8120NK 8x8, 120-Inch Hinge Cover Wireway, No Knockouts

The CWST8120NK is the 120 in (3,048 mm) hinge cover straight section for 8 x 8 in Type 1 lay-in wireway, the longest length listed for this cross-section, supplied without knockouts. One piece carries cable across 120 in of an indoor run with fewer joints, which suits plant wiring and machine building crews covering long walls or ceilings.

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 59.94 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 CWST8120, and a screw cover version without knockouts as CWSC8120NK.

Nominal size is 8 in x 8 in x 120 in (203 mm x 203 mm x 3,048 mm). The drawing shows a 8 in x 8 in inside cross-section, a cover width of 8.42 in and outside body dimensions of 8.14 in. Shipping weight is 50 lbs (22.68 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 CWHW8 and the ceiling type is CWHD8. Effective May 4, 2026, joiners are no longer included with straight sections, so order the 8 x 8 joiner CWJO8 separately as required.

The CWST8120NK 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.
