Hammond CWST418NK 4x4x18" Lay-In Hinge Cover Wireway, No Knockouts

The CWST418NK is a 1.5 ft (18 in) straight section of Type 1 lay-in hinge cover wireway, built without knockouts in gray steel. Its 4 x 4 in cross-section is one of the cross-sections offered in the knockout-free series, which runs from 2.5 x 2.5 up to 12 x 12. It is intended for electricians, panel builders and OEM machine builders who need an enclosed channel to route and protect wiring.

The section measures 4 in x 4 in x 18 in (102 mm x 102 mm x 457 mm), with 4 in inside dimensions and outer drawing dimensions of 4.36 in / 4.11 in / 4.06 in. A single hinged door, 17.94 in long on the drawing, runs the length of the section, so conductors can be laid in from the front rather than pulled through.

This w/o KO version is supplied without knockouts. The drawing shows 0.27 in and 0.31 in diameter holes, with 17.00 in spacing shown on the bottom view. Shipping weight is 7.2 lbs (3.27 kg).

Hammond's lay-in wireway is part of a system of sections, elbows, tee fittings and other components for protecting cabling in machine building and general plant wiring.
