Metallics RCT31 – Frequently Asked Questions
1) What thread size does the Metallics RCT31 rod coupling take?
The RCT31 coupling is threaded 3/4-10, so it mates with 3/4 inch all-thread rod at 10 threads per inch, the standard UNC pitch for that rod diameter. Thread both rod ends into it and you extend a hanger rod run without welding or splicing.
2) Will the Metallics RCT31 work with 1/2-13 or 3/8-16 threaded rod?
No. The RCT31 is a 3/4-10 coupling only, so 1/2-13 or 3/8-16 rod will not thread into it. Order the coupling that matches the rod diameter and pitch you are hanging with; a smaller rod needs a smaller coupling.
3) Is the Metallics RCT31 rod coupling hex or round?
Hex body. The flats let you hold the coupling with a wrench while you run rod into it from both ends, which matters when you are tensioning a long hanger drop overhead.
4) What material and finish is the RCT31 coupling, and can it go in a damp area?
Steel with a zinc plating. Zinc plate handles normal indoor and dry interior commercial work. For wet, exterior, corrosive, or washdown environments, specify a stainless or hot dip galvanized coupling instead.
5) How many rod couplings come in a jar of Metallics RCT31?
25 pieces per jar. That is the pack type, so an order quantity of one gets you a jar of 25 rather than a single coupling. Useful if you are splicing rod across a whole floor of conduit or strut hangers.
6) What do electricians use a 3/4-10 rod coupling for?
It joins two lengths of 3/4 inch threaded rod end to end. Typical uses are extending a hanger drop that came up short, splicing stock rod lengths to reach a high deck, or tying rod to a 3/4-10 threaded insert or anchor for conduit racks, strut trapeze, and fixture support.
7) Do I need anything else besides the RCT31 to splice threaded rod?
Just the rod itself. The coupling is the only piece required for the splice, and nothing else ships with it. If your spec calls for a jam nut at the coupling or a hanger nut and washer at each end point, order those separately.
8) Is the Metallics RCT31 ordered as a single part number?
Yes, it is a single model, RCT31, with no finish or size options to choose. Specify the part number and the jar quantity you need.
