Thomas & Betts 1245 – Frequently Asked Questions

1) What size combinations does the Thomas & Betts male enlarger come in?
Three size steps are offered: 1/2 inch to 3/4 inch (model 1245), 1 inch to 1-1/4 inch (model 1244), and 1-1/4 inch to 1-1/2 inch (model 1247). Each one steps up one trade size, so if you need to jump two sizes you'll need to stack fittings or use a different reducer.
2) Will this enlarger thread onto rigid metal conduit and IMC?
The enlarger uses standard tapered conduit threading, so it mates with threaded rigid and IMC conduit and with threaded hubs of the matching trade size. EMT is not threaded, so you'd need a threaded EMT connector first and then the enlarger on that.
3) I need to go from 3/4 inch conduit up to 1 inch. Does Thomas & Betts make this enlarger in that size?
No. The three steps available are 1/2 to 3/4, 1 to 1-1/4, and 1-1/4 to 1-1/2 inch. A 3/4 to 1 inch step is not among them, so for that transition look to a different fitting or a threaded coupling and nipple combination.
4) Is the Thomas & Betts male enlarger metal or plastic?
Malleable iron throughout, including the threads. That matters on an industrial run where the fitting takes mechanical load or gets wrenched tight, and it keeps thread integrity better than a die-cast or plastic bushing.
5) Can I order the Thomas & Betts male enlarger by part number for a submittal?
Yes, each size is its own Thomas & Betts part number: 1245 for 1/2 x 3/4 inch, 1244 for 1 x 1-1/4 inch, and 1247 for 1-1/4 x 1-1/2 inch. Specify by that number rather than by size alone so the right step lands on the job.
6) Do I need thread sealant when installing a conduit enlarger?
Thread the male end onto the 1/2 inch conduit or hub with a threading compound, then bring the larger conduit into the enlarged end with full thread engagement and tighten with a wrench. Cut and deburr the conduit ends first so the connection seats square and the wire pull doesn't snag.
