Topaz Lighting 671S – Frequently Asked Questions

1) Can I use the Topaz 671S set-screw connector on rigid conduit without threading the ends?
That's the point of it. The Topaz 671S is a threadless set-screw connector for rigid and IMC conduit, so you cut the conduit, slip it in, and tighten the set screw against the wall of the pipe. No die work, no threading the field end. It lands the conduit on a box or enclosure knockout with a locknut connection.
2) Is a set-screw rigid connector rated for outdoor or wet locations?
Yes. The Topaz 671S series is UL Listed and rated for both dry and wet locations, with the malleable iron body giving corrosion resistance in damp and moisture-prone spots. That covers exterior walls, mechanical rooms and washdown-adjacent runs.
3) Can these set-screw connectors be poured in concrete?
They are concrete-tight when taped. Tape the joint before the pour and the Topaz set-screw rigid connector is suitable for embedded and concrete-encased runs. Untaped, it is not a concrete-tight fitting, so if you skip that step use a fitting that is concrete-tight as supplied.
4) What trade sizes do the Topaz malleable iron set-screw rigid connectors come in?
Trade sizes run 1/2 inch through 2 inch. The orderable sizes are 1/2 inch (671S), 3/4 inch (672S), 1 inch (673S), 1-1/2 inch (675S) and 2 inch (676S), so one part family covers most branch and feeder runs.
5) Is a set-screw connector or a threaded fitting the right choice for rigid conduit?
Threaded couplings and connectors give you a threaded, fully bonded joint and are what most specs call for on exposed rigid runs. The Topaz 671S set-screw type is for when you don't want to thread in the field, cut ends on an existing run, retrofits, tight ceiling work. It still bonds rigid or thin-wall conduit to the box, and it is UL Listed for dry and wet locations. If the drawing specifically calls out threaded rigid terminations, follow the drawing.
6) I need to standardize rigid conduit terminations across a facility, does one part number cover it?
One family does. The Topaz set-screw rigid connector runs 671S through 676S across 1/2 inch to 2 inch, all malleable iron, all UL Listed, all rated dry and wet location. Stocking that range in the 100-piece packs covers branch through feeder terminations on rigid and IMC with a single fitting type and one install method for your crews.
7) How are Topaz 671S connectors packaged, and can I buy just a few?
They are packed 100 per unit. That is a contractor pack, sized for rough-in work where you are landing dozens of terminations on a single job rather than picking up a handful for one repair.
8) Why malleable iron instead of die-cast zinc for a conduit connector?
Malleable iron takes impact and mechanical abuse better than die cast, which matters where conduit gets knocked, on industrial floors, loading areas, exposed plant runs. The Topaz set-screw rigid connectors are malleable iron throughout the 1/2 inch to 2 inch range, and the same material is what gives them their wet-location corrosion resistance.
