Hammond CWST612NK 6x6, 12-Inch Hinge Cover Wireway, No Knockouts

The CWST612NK is a 12 in (305 mm) hinge cover straight section for 6 x 6 in Type 1 lay-in wireway, supplied without knockouts. It is the shortest 6 x 6 hinge cover length in the ordering table, a compact piece for electricians and panel builders assembling indoor wireway runs from shorter sections.

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 a single 11.94 in hinged cover. 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 CWST612, and a screw cover version without knockouts as CWSC612NK.

Nominal size is 6 in x 6 in x 12 in (152 mm x 152 mm x 305 mm). The drawing shows a 6 in x 6 in inside cross-section, a cover width of 6.36 in and outside body dimensions of 6.11 in x 6.06 in. Shipping weight is 10 lbs (4.54 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 CWHW6 and the ceiling type is CWHD6. Effective May 4, 2026, joiners are no longer included with straight sections, so order the 6 x 6 joiner CWJO6 separately as required.

The CWST612NK 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.
