No. The 4448 HS is a NEMA 1 enclosure, which is general purpose indoor only. It has no gasketing and the hinged cover is secured with plated screws, so keep it inside dry areas such as mechanical rooms, electrical rooms, or plant interiors. For a washdown bay, loading dock, or any location exposed to rain, you need a NEMA 3R or 4 raintight wireway instead.

It is a 4 x 4 inch cross section, 48 inches long: 4 inch height, 4 inch width, 48 inch length. That 4 x 4 trough is the standard size lay-in wireway used for gutter runs above panelboards and control cabinets. It weighs 13.488 lb, so a single person can set a stick in place before bolting it up.

No. The 4448 HS has a hinged cover, so it swings open and stays with the body while you lay conductors in. That is the practical difference from a screw cover wireway, where the lid comes off completely and gets set on the floor or dropped. Plated screws secure the cover to the body when it is closed.

It mounts with thru holes in the body, so it bolts directly to a wall, backboard, or strut run using your own hardware. Mounting fasteners and support brackets are not part of the wireway itself, so order channel, straps, or hangers separately for the run you are supporting.

The 4448 HS carries CSA C22.2 certification, which is the Canadian standard series inspectors look for on enclosures. That covers the Canadian side of a spec that calls for a certified NEMA 1 steel wireway.

16 gauge steel, painted ANSI 61 gray. That is the same gray used on most commercial panelboards and control enclosures, so a run of it above a lineup of gear matches visually without repainting.
