Metallics RCTL29 – Frequently Asked Questions
1) What thread size does the Metallics RCTL29 rod coupling take?
The RCTL29 coupling is tapped 1/2-13, so it joins 1/2 inch threaded rod with standard UNC coarse thread (13 threads per inch). It will not accept 3/8-16 or 5/8-11 rod, so match the coupling to the rod diameter you are hanging with.
2) Can I use a rod coupling to splice two pieces of threaded rod instead of ordering a longer piece?
That is exactly what the RCTL29 is for. Thread 1/2-13 rod into each end of the 1-3/4 inch hex coupling and you get a continuous run, which is how most contractors extend a hanger drop when the stock rod length falls short. Keep the splice engagement even on both ends, and keep couplings out of locations where a threaded splice is not permitted by the job spec.
3) Is this coupling a hex body or a round one, and can I tighten it with a wrench?
Hex body. The flats let you hold or drive the coupling with a standard wrench or socket while you thread rod in from both ends, which matters when you are extending a hanger run overhead and cannot spin the rod itself.
4) Is the Metallics RCTL29 coupling plated for indoor electrical and mechanical hanger work?
It is steel with a zinc plating, the usual finish for interior threaded rod hanger assemblies supporting conduit, strut, cable tray, and similar loads. For wet, exterior, or corrosive environments, specify a stainless or hot-dip galvanized coupling instead.
5) Will a 1/2-13 rod coupling work with threaded rod hangers for conduit and strut?
Yes, provided the rod is 1/2 inch diameter with coarse 1/2-13 thread, which is the common size for conduit hangers, strut trapeze, and cable tray drops. The coupling only joins rod to rod, so you still need your own rod, nuts, washers, and strut or beam attachment to finish the assembly.
6) How many rod couplings come in a jar of Metallics RCTL29?
They ship 25 to a jar, packaged as a jar rather than loose or bulk boxed. That is a practical count for stocking a service van or a hanger kit on a conduit rough-in, since you typically use a coupling at every rod splice.
