All-Thread Rod Coupling Alignment

For this hanger rod coupling, how many threads should be engaged? Should I use jam nut for extra security?

I'm checking all-thread rod coupling alignment at [location]. I found threaded coupling joining two pieces of all-thread rod in hanger assembly. For this hanger rod coupling, how many threads should be engaged? Should I use jam nut for extra security?

Stop if

Hold point on all-thread rod coupling alignment: I have the location, photo, drawing/detail, and what was checked. Who should verify before this gets cut, covered, lifted, sealed, energized, or signed off?

Watch out

Don't install couplings with partial thread engagement. Don't use couplings in seismic bracing without engineer approval. Don't assume couplings as strong as continuous rod.

Check
