What do I do if a drop-in anchor was never set with the tool?
An un-set drop-in anchor is an overhead failure waiting to happen. Pull the rod, set or replace the anchor correctly, and verify it before loading duct.
Do not hang duct from a drop-in anchor that was only dropped in and threaded.
Check
Look for rods that pull, spin, or feel loose under hand load.
Confirm the setting tool was used on each drop-in anchor.
Check hole size/depth and anchor type.
Replace damaged or spinning anchors.
Verify before lifting or reloading duct.

Say this to your foreman
This hanger anchor at [location] was threaded but does not look set. I stopped loading the run. Do you want every anchor in this section checked and reset/replaced before we lift duct?
