Metallics RCT28SS – Frequently Asked Questions
1) What thread size does the Metallics RCT28SS rod coupling take?
The RCT28SS coupling is threaded 3/8-16, so it joins standard 3/8 inch threaded rod with 16 threads per inch (UNC). Both ends take the same 3/8-16 thread, so it couples two lengths of rod end to end. If your hanger rod is 1/4-20 or 1/2-13, this is the wrong size.
2) Will the RCT28SS work on my 3/8 inch all-thread hanger rod for conduit supports?
Yes, provided the rod is 3/8-16 coarse thread, which is what most 3/8 inch all-thread hanger rod is. The coupling threads over both rod ends to make the splice. Run the rod in far enough from each side that the thread engagement is roughly equal, since a coupling only carries load through the threads that are actually engaged.
3) Is the RCT28SS rod coupling stainless steel or plated steel?
Stainless steel. The SS in RCT28SS is the material, which is why it gets specified for damp, exterior, coastal, or wash-down areas where a zinc-plated coupling would rust. For dry interior hanging, a plated steel coupling is the usual cheaper choice.
4) How many rod couplings come in a jar of Metallics RCT28SS?
Fifty pieces, packed in a jar. That is the pack unit, so an order quantity of one gets you 50 couplings, not a single piece. Worth knowing if you only need a handful for one trapeze run.
5) What is a hex rod coupling used for on an electrical or mechanical install?
A hex rod coupling splices two pieces of threaded rod together to extend a drop, which is what you need when the deck height leaves you short on a conduit trapeze, strut hanger, or fixture drop. The hex body lets you drive it with a wrench instead of trying to turn a round nut by hand. The RCT28SS does this in 3/8-16 stainless.
6) Can I use a stainless rod coupling with galvanized or plated threaded rod?
It threads on fine mechanically as long as the rod is 3/8-16. The thing to weigh is that mixing stainless with zinc or galvanized in a wet location sets up dissimilar metal corrosion at the joint, so for exterior or wash-down work most specs call for stainless rod with the stainless coupling.
