Metallics RCA381 – Frequently Asked Questions
1) What rod size does the Metallics RCA381 rod coupling anchor take?
The RCA381 is a 3/8 inch rod coupling sleeve anchor, so it accepts 3/8 inch threaded rod or hanger rod threaded directly into the sleeve. Overall length is 1-7/8 inches, which is the embedment depth you need to plan for in the concrete.
2) Can I hang electrical conduit and strut from the Metallics RCA381 anchor?
That is exactly the application it is built for. A rod coupling sleeve anchor sets into concrete and gives you a female 3/8 inch thread at the surface, so 3/8 inch rod drops for conduit hangers, strut trapezes, and light fixture supports thread straight in with no nut or washer on top. It is carried as electrical fastening hardware.
3) How many anchors come in a box of Metallics RCA381?
They ship 100 to a box, packaged as a box rather than a bag or carded pack. That quantity suits a full trapeze or conduit hanger run rather than a single drop.
4) What is the difference between a rod coupling anchor and a wedge anchor or drop-in anchor?
A rod coupling sleeve anchor like the RCA381 is threaded internally and sits flush, so the rod can be installed and removed later without touching the anchor. A wedge anchor is a stud that sticks out of the concrete permanently and needs a nut, which is awkward for overhead rod work. A drop-in is also internally threaded but requires a setting tool to expand it. For overhead 3/8 inch rod drops, the coupling sleeve style is the one most electricians reach for.
5) Is the Metallics RCA381 for concrete or can it go in drywall or block?
Sleeve-style rod coupling anchors are concrete anchors. They work by expanding against the wall of a drilled hole in solid concrete and will not hold in drywall, and hollow block is not a substrate they are intended for. For drywall or hollow masonry you need a toggle or a hollow-wall anchor instead.
6) What part number do I order for a 3/8 inch Metallics rod coupling anchor?
Order Metallics RCA381. That is the manufacturer part number for the 3/8 by 1-7/8 inch rod coupling sleeve anchor, supplied 100 per box.
