Metallics RCT28V – Frequently Asked Questions
1) What thread size does the Metallics RCT28V rod coupling take?
The RCT28V coupling is threaded 3/8-16, so it joins standard 3/8 inch all-thread hanger rod with 16 threads per inch. If your rod is 1/2-13 or 1/4-20, this is the wrong coupling for it.
2) How does the Metallics RCT28V rod coupling ship, and can I buy just a few?
It comes as a box of 500 pieces, so it is a contractor or stockroom quantity rather than a one-off part. That is the right buy if you are hanging a long run of conduit, strut, or pipe and need to extend rod at many points.
3) What is the Metallics RCT28V coupling made of and is it plated for damp locations?
Steel with zinc plating. Zinc plated steel is fine for dry and normally damp indoor runs, but for corrosive or exterior exposure you'd want stainless rod hardware instead.
4) What do electricians actually use a 3/8-16 rod coupling for?
Joining two lengths of 3/8 inch threaded hanger rod end to end. On an electrical job that usually means extending drop rod from a concrete insert or beam clamp down to trapeze supports, strut, or conduit hangers when a single stock rod length will not reach the ceiling height.
5) Do I get rod or nuts with the Metallics RCT28V, or just the couplings?
Just the couplings, 500 to the box. The threaded rod itself, plus any hex nuts, washers, beam clamps or hangers your detail calls for, are ordered separately.
