Metallics RCT33 – Frequently Asked Questions
1) What thread size does the Metallics RCT33 rod coupling take?
The RCT33 is a 7/8-9 coupling, meaning it threads onto 7/8 inch diameter rod with 9 threads per inch (standard UNC for that diameter). It will not accept 1/2-13, 5/8-11, or 3/4-10 rod; those need the matching coupling size for that thread.
2) Is the RCT33 rod coupling hex or round?
Hex body, which lets you put a wrench on it when you are drawing two lengths of 7/8 inch rod together overhead. Round couplings have to be turned by hand or with pliers.
3) What material and finish is the Metallics RCT33 coupling, and is it OK for damp indoor areas?
Steel with a zinc plating. Zinc plated steel is the normal choice for dry and intermittently damp interior work such as mechanical rooms and above ceilings. For sustained wet or corrosive exposure, specify a stainless or hot dip galvanized coupling instead.
4) Can I use a rod coupling to extend threaded hanger rod instead of buying a longer piece?
That is what the RCT33 is for. It joins two lengths of 7/8 inch threaded rod end to end so you can make up a drop longer than the stock rod you have on the truck. Run both rod ends fully into the coupling so the threads are engaged across the full body, and keep the splice out of the bend or shear path of whatever it supports.
5) How many rod couplings come in a box of Metallics RCT33?
They ship 100 per box, packaged as a box pack. That is a contractor quantity for a job where you are splicing or extending a lot of 7/8 inch hanger rod, not a single-piece buy.
6) What is the part number to order the 7/8-9 hex rod coupling from Metallics?
Order it as Metallics RCT33. That is the manufacturer part number for the 7/8-9 hex steel zinc rod coupling.
