B-LINE 4448-12FW – Frequently Asked Questions

1) Is the B-Line 4448-12FW wireway rated for washdown or oily environments?
The 4448-12FW is a NEMA 12 wireway with a seamless poured in-place gasket, so it is built to keep out dust, falling dirt, and dripping non-corrosive liquids, oil and coolant seepage included. It is not a NEMA 3R or 4X enclosure, so do not use it outdoors or where it will be hosed down directly.
2) Does this wireway have a hinged cover or a screw-on cover?
Hinged. The cover swings on heavy-duty hinges and is held shut with screw clamps, so you are not fishing loose screws out of a pan while you pull wire, and the cover stays with the trough. Screw-cover troughs are the alternative if you want the cover fully removable for a straight lay-in.
3) Do I need anything else besides the wireway sections to build out a run?
A 48 inch straight section is only part of a system. Direction changes, tees, and end closures are separate fittings in the 12FW family, and the wireway hangers used to support it are ordered on their own. Count your straight lengths in 48 inch increments, then add the elbows, tees, connectors, and closing plates the layout calls for.
4) What are the actual cross section and length of the 4448-12FW wireway?
It runs 4 inches by 4 inches in cross section and 48 inches long, and weighs 20.276 lb per section. That 4 x 4 trough is the common size for feeder taps and control wiring pulls; if your conduit fill or wire bending space needs more room, step up to a 6 x 6 trough instead.
5) How is a 48 inch B-Line 12FW wireway section supported?
It mounts with wireway hangers, which is the standard trapeze or wall-bracket support method for this trough family. The hangers are a separate order item, so plan support spacing and quantity for each 48 inch section before the job.
6) Is this B-Line wireway approved for use in Canada?
The 4448-12FW carries CSA C22.2 certification, so it is acceptable for Canadian installations as well as US work.
7) What is the exact part number to order this 4 x 4 x 48 inch hinged NEMA 12 wireway?
Order Eaton B-Line part number 4448-12FW. The number reads as the trough size and length (4 x 4 x 48) followed by the 12FW series designation for the NEMA 12 hinged-cover family.
8) What gauge steel is the B-Line 4448-12FW made from, and what color does it ship in?
14 gauge steel, finished in ANSI 61 gray. That is the same gray used on most industrial panelboards and control enclosures, so a run will match existing gear in a plant or mechanical room without repainting.
