Square D LDB4C – Frequently Asked Questions

1) What does the Square D LDB4C wireway fitting actually do in a Square-Duct run?
The LDB4C is a 180 degree connector for Square D Square-Duct wireway. It reverses the direction of the wireway run a full 180 degrees, so you can double a run back on itself without building the turn out of separate splice fittings. It is a fitting, not a wireway section, so you still order straight duct lengths for the run itself.
2) Can I use this 180 degree Square-Duct connector outdoors or in a washdown area?
No. The LDB4C is a NEMA 1 enclosure fitting with N1 paint, which covers general purpose indoor use, protection against dust and incidental contact. Outdoor, wet location, or washdown runs need a wireway with an enclosure rating for those conditions, not this one.
3) Is the Square D Square-Duct 180 degree connector approved for code-compliant commercial work in the US and Canada?
It is UL Listed and CSA certified, which is what an inspector looks for on industrial and commercial wireway installs on either side of the border.
4) Will the Square D LDB4C connector bolt up to Square-Duct wireway from other manufacturers?
Treat it as a Square-Duct component only. The LDB4C is built to match the fit and finish of the Square D Square-Duct wireway family, and that is the system it is stated to connect. Mixing brands of wireway fittings is not something the product data supports.
5) Which part number do I order for the 180 degree Square-Duct connector?
One model covers it: LDB4C, the Square D Square-Duct 180 degree connector in NEMA 1. There are no finish or size options to specify on it, the N1 paint is factory applied.
6) Is this Square-Duct connector suitable for shop-built OEM control panels?
Yes. It is aimed at panel builders, system integrators, and contractors assembling or extending Square-Duct wireway, either in the shop or in the field, in indoor NEMA 1 environments such as control panel wiring systems.
7) Does the Square D LDB4C contain mercury or toxic heavy metals for our environmental spec?
No. The Square-Duct 180 degree connector is stated mercury free and free of toxic heavy metals, which is what most institutional and green-build submittals are asking for.
