Metallics TRS610D – Frequently Asked Questions
1) Is TRS610A the same rod as the Metallics TRS610D?
Yes. TRS610A is the old part number for what is now sold as TRS610D, the 1/4-20 x 10 foot zinc plated steel rod. If a drawing or an old purchase order calls out TRS610A, TRS610D is the current designation.
2) Can I use 1/4-20 zinc plated threaded rod to hang conduit and fixtures indoors?
Zinc plating is a light sacrificial coating meant for dry, protected interior use, which covers most conduit trapeze, strut, junction box and lay-in fixture hanging. For outdoors, washdown areas, pool rooms or anywhere exposed to moisture or chemicals, go to a hot dip galvanized or stainless rod instead, because zinc plating will rust in those conditions.
3) Can a 10 foot threaded rod be cut down to the drop lengths I need?
Yes, that is the normal way it gets used. The 10 foot stick of 1/4-20 zinc rod is cut on site with a bandsaw, chop saw or rod cutter to whatever drop each hanger needs. Chase the cut end with a 1/4-20 nut to clean up the threads, and touch up the bare cut with cold galvanizing or zinc paint if the end will be exposed.
4) Is 1/4-20 rod heavy enough, or should I step up to 3/8-16 for my hanger?
1/4 inch rod is the light duty size, used for single small conduit runs, lay-in troffers, small boxes and light signage. Once you are carrying a trapeze with multiple conduits, cable tray, larger luminaires or anything with vibration or seismic bracing requirements, specifiers normally move to 3/8-16 or 1/2-13 rod. Follow the load value the engineer or hanger manufacturer publishes for the rod size rather than sizing by feel.
5) Is the Metallics TRS610D threaded rod made in the USA?
Yes, the TRS610D 1/4-20 x 10 foot zinc plated steel rod is USA made, which matters on public works and federally funded jobs that carry domestic material requirements.
6) What nuts and hardware do I need to order with 1/4-20 threaded rod?
The rod ships as plain rod, so the connecting hardware is a separate line. For a typical hanger you will want 1/4-20 hex nuts, flat washers, and whatever anchor or strut fitting goes into the deck, plus 1/4-20 rod couplings if you need to splice beyond 10 feet. All standard 1/4-20 coarse thread components thread onto it.
