Metallics RCT29C – Frequently Asked Questions
1) Can I use the RCT29C to splice 3/8 inch threaded rod?
No. The RCT29C is tapped 1/2-13 only, so 3/8-16 rod will spin loose in it with no thread engagement. For 3/8 inch hanger rod you need a 3/8-16 coupling; for mixed sizes use a reducing coupling instead.
2) What is the Metallics RCT29C rod coupling made of and is it plated?
Steel with a zinc plating, per the St-zn designation. Zinc plated steel is intended for dry indoor hanger and trapeze work; for wet, corrosive, or exterior runs you want a stainless or hot dip galvanized coupling instead.
3) How many Metallics RCT29C couplings come in a box?
They ship 100 to a box, packaged as a box pack. That is a quantity sized for a full hanger or trapeze layout on a commercial job rather than a single repair, so contractors extending rod drops across a ceiling grid usually buy by the box.
4) What is a threaded rod coupling used for on an electrical job?
A rod coupling joins two pieces of threaded rod end to end to extend a hanger drop, or connects rod to a threaded insert or beam clamp stud. On electrical work that is typically supporting conduit racks, cable tray, strut trapezes, or light fixtures from the structure above. The RCT29C handles 1/2-13 rod, the common size for heavier conduit and tray runs.
5) Is the RCT29C coupling hex shaped, and does that matter for installation?
It is a hex body coupling, which means you can hold it with a standard wrench while you spin rod into either end. That matters when you are joining two lengths of threaded rod overhead and need to torque the joint rather than hand tight it.
6) What part number do I order for a Metallics 1/2-13 hex rod coupling?
Order Metallics RCT29C. That is the manufacturer part number for the 1/2-13 zinc plated steel hex rod coupling supplied 100 per box.
