Topaz Lighting 781 – Frequently Asked Questions

1) What sizes does the Topaz 781 EMT offset connector come in, and what are the part numbers?
Two trade sizes: 1/2 inch is part number 781 and 3/4 inch is part number 782. Both are the same compression-type offset connector for EMT, so order by the trade size of the tubing you're terminating.
2) Will a compression EMT connector work outdoors or in a wet location box entry?
The Topaz 781 offset connector is UL Listed and rated for both indoor and outdoor use, and the compression body makes a concrete-tight connection at the box entry. That covers exterior enclosure entries and pours in masonry or concrete work. Concrete-tight is not the same designation as raintight, so match the fitting rating to what your inspector is calling for on the job.
3) Will this Topaz connector work on rigid conduit or flex?
No. The 781 is built for EMT (thin-wall) only. Rigid and IMC use threaded couplings or fittings sized for that wall, and flex needs its own connector, so neither will seat correctly in this compression gland.
4) What does the offset on this EMT connector actually do on an install?
The offset bends the run so EMT coming down a wall or across a surface can enter a metal outlet box or enclosure without you having to bend an offset into the tubing itself. It cuts a step out of the raceway layout and saves a separate fitting at the box. Straight EMT compression connectors are the choice when the conduit already lines up with the knockout.
5) Compression or set screw EMT connector, which should I use?
Compression, like the Topaz 781, tightens a gland nut around the tubing and gives a concrete-tight termination with no set screws to back out. That's what you want in slabs, masonry and outdoor enclosure entries. Set screw fittings are cheaper and fine for dry indoor exposed work where concrete-tight isn't required.
6) Is a zinc die-cast fitting durable enough for industrial or exterior conduit runs?
The body is zinc die-cast, chosen for corrosion resistance and mechanical strength in both interior and exterior installations. Topaz lists it for commercial and industrial raceway, concrete and masonry work, and outdoor enclosure entries. For heavily corrosive chemical environments, spec a fitting rated for that specific exposure.
7) Do I need a locknut or bushing with this EMT offset connector?
The 781 terminates EMT into a metal outlet box or enclosure knockout, and that termination is made up on the inside of the box. Plan on the standard hardware and any bushing your local code calls for at the box; order those separately from the connector.
