Thomas & Betts LB400M – Frequently Asked Questions

1) What trade sizes does the Thomas & Betts Series 35 LB conduit body come in?
Two trade sizes are offered in the Series 35 LB: 1/2 inch, ordered as LB50M, and 4 inch, ordered as LB400M. Match the trade size to the conduit run it threads onto, since the hubs are threaded for that size and nothing else.
2) Will the Thomas & Betts LB50M thread onto 1/2 inch rigid conduit?
Yes. The LB50M is a threaded 1/2 inch trade size body, so it takes standard 1/2 inch NPT conduit thread and mates with threaded rigid or IMC. It is not a set-screw or compression fitting, so EMT needs a threaded adapter to land on it.
3) Is the Series 35 LB body malleable iron or aluminum?
Malleable iron. That is the heavier, impact-resistant choice for industrial and commercial work, and it holds thread form well on the hubs. If your spec calls for copper-free aluminum on an aluminum rigid run, this is not the body to use.
4) How deep is the 1/2 inch Series 35 LB body?
The 1/2 inch version has a net depth length of 4-11/16 inches. Use that when you are figuring clearance behind a wall penetration or spacing the body off a strut or panel.
5) Can I use a 4 inch LB conduit body for a service entrance turn?
The LB400M is the 4 inch malleable iron body in the Series 35 line, which is the size range used on large feeders and service conduit. Keep in mind that conductor fill and bend space rules govern whether a body of that size is acceptable as a pull point on your run, so size the body to the conductors, not just to the pipe.
