Metallics RCTR29 – Frequently Asked Questions
1) What thread sizes does the Metallics RCTR29 rod coupling join?
The RCTR29 is a reducing rod coupling that takes 1/2-13 threaded rod on one end and 3/8-16 on the other. It lets you step a 1/2 inch hanger rod down to 3/8 inch (or the reverse) without changing the whole drop.
2) Can I use a reducing rod coupling to splice two pieces of the same size threaded rod?
No. The RCTR29 has two different threads, 1/2-13 on one side and 3/8-16 on the other, so it will only join a 1/2 inch rod to a 3/8 inch rod. To extend two lengths of the same diameter rod you need a straight (same-thread) coupling in that size instead.
3) Is the Metallics RCTR29 coupling plated for use in damp areas?
It is zinc plated steel, which is the standard finish for interior and dry-to-damp hanger work. For wet, corrosive, or exterior-exposed runs, specify a stainless or hot-dip galvanized coupling rather than zinc plated.
4) What shape is the RCTR29 rod coupling body, and can I wrench it?
The body is hex, so you can hold or drive it with a standard open-end or socket wrench while threading rod in from either end. That is the difference from a round-body coupling, which has to be turned by hand or with a pipe wrench.
5) Where does a 1/2 to 3/8 reducing rod coupling get used on an electrical or mechanical install?
It is used where a hanger drop changes rod diameter midway, for example a 1/2 inch rod anchored to the structure carrying a 3/8 inch rod down to trapeze, strut, conduit hanger, or fixture support. It also saves a run when the anchor insert in the deck is one thread size and the hardware below is another.
6) How many Metallics RCTR29 rod couplings come in a jar?
They ship 25 pieces to a jar, which is the pack type for this item. Plan quantities in multiples of 25 if you are stocking a truck or an MRO crib.
