Square D LDB45 – Frequently Asked Questions

1) Can I use this Square D wireway outdoors or in a washdown area?
No. The LDB45 is NEMA 1, which is indoor general-purpose only, with no protection against rain, hose-down, or dust ingress. For a wet or outdoor location you need a NEMA 3R or 4 rated trough instead.
2) Does the Square-Duct wireway come with knockouts for conduit entry?
No knockouts. The LDB45 is 16-gauge steel with a blank body, so you drill or punch your own conduit entries wherever the run needs them. Plan on a hole punch set and bushings or conduit hubs as part of the install.
3) Is this wireway UL Listed for a commercial inspection?
Yes. The Square-Duct wireway is UL Listed and also CSA certified, which covers code-compliant commercial and industrial installs on both sides of the border.
4) What is the closest 4 x 4 wireway alternative to the Square D LDB45?
The Milbank 4448-GSC1 is the nearest match in cross-section. It is a BP44 series NEMA 1 wireway trough in 4 in x 4 in x 4 ft. The Square D LDB45 is also a 4 in x 4 in NEMA 1 wireway, but in a 5 ft section with a hinged cover, while the Milbank uses a screw cover. If you want 4 ft runs or prefer a screw-on cover, go Milbank; if you want 5 ft sections and a cover that swings open for access, stay with the LDB45.
5) Is the cover hinged or screw-on on the Square D LDB45?
Hinged. The cover swings open rather than coming off as a loose panel, so you are not juggling a cover and a handful of screws on a ladder when you pull or splice conductors. If your spec calls for a screw cover instead, the Milbank BP44 Series 4 in x 4 in x 4 ft trough is a screw-cover NEMA 1 unit.
6) What is the finish on the Square D Square-Duct, and will it hold up in an unheated plant?
Gray polyester powder coating over steel, ANSI 49 gray. It is a corrosion-resistant painted finish for indoor service. For damp or more aggressive environments, a galvanized body such as the Hoffman Econotrough galvanized steel wireway is the different construction to look at.
7) I need a shorter 4x4 trough section to finish a run. What are my options?
The Square D LDB45 is a 5 ft section. If a 5 ft length overshoots the opening, the Milbank BP44 Series trough is a 4 in x 4 in NEMA 1 section in a 4 ft length, and the Milbank BP102 Series 10 x 10 comes in 2 ft. Fittings and couplings between brands are not interchangeable, so keep a single run in one system.
8) Hinged cover versus lay-in wireway - which do I want for a long cable run?
The Square D LDB45 Square-Duct uses a hinged cover, so the cover swings open along the length for access during pulls and later maintenance without handling loose panels. Hoffman's lay-in style sections, such as the F44T148G F Series and the F1010T straight section, are designed so conductors lay into the trough from the side. Both styles let you drop wire in rather than fish it; the hinged cover on the LDB45 keeps the cover captive to the body, which some installers prefer on overhead runs.
9) I only need a short 2 ft section of trough - is there a shorter option than the 5 ft LDB45?
The Square D LDB45 Square-Duct comes as a 5 ft straight-length section. For shorter runs, the Milbank 101024-GSC1 is a 2 ft trough and the Milbank 101048-GSC1 is a 4 ft - both in a 10 x 10 cross-section rather than 4 x 4. The Hoffman Econotrough F6636RTG comes in a 36 in length. Note that stepping to those options changes the cross-section and the cover style, so confirm fittings and conduit entries before substituting.
10) Can I mix the Square D LDB45 with Milbank or Hoffman sections in the same run?
Treat them as separate systems. The Square D LDB45 is a Square-Duct series section, Milbank troughs run in series families such as BP44, BP101, BP102, and BP104, and Hoffman uses the F Series and Econotrough. Couplings, connectors, and cover hardware are designed within each series, so a continuous run should be built from one series and transitions between manufacturers should be made at an enclosure or junction rather than by bolting dissimilar sections together.
11) Where is the Square D LDB45 wireway made?
Mexico. That matters on jobs with country-of-origin reporting on the submittal package, so it is worth noting before you cut the PO.
12) The LDB45 has no knockouts - what if I want a wireway with entries already punched?
The Square D LDB45 Square-Duct is supplied without knockouts, so every conduit entry is field-drilled where you want it. If you would rather not lay out and punch the body, a lay-in style section such as the Hoffman F44T148G in the F Series, offered in 14/16 gauge steel, is the alternative family to look at for your opening configuration. For a run where entry locations are still being coordinated, the unpunched LDB45 is often the safer buy.
