If the drawing shows a brace symbol, angle note, restraint tag, or structural detail callout, slow down. Seismic bracing is approved-detail work, not normal hanger guessing.
Look for brace symbols, detail bubbles, arrows, angle notes, or sheet references like S-##.
Find the matching structural/mechanical detail before installing or moving hardware.
If the symbol or detail is not clear, photo the note and ask before touching the brace.

In Seismic Bracing, Sway Control & Structural Coordination, I’m looking at: What do I do when not recognizing when seismic bracing applies? What should I verify before I cut, drill, seal, cover, move, or install?
Do not
Do not modify or copy bracing/rigging from another area just because it looks similar.
Why it matters
Seismic brace symbols can look like small plan notes, but they control engineered restraint details. Missing the symbol can turn a normal hanger task into a failed inspection or unsafe support condition.
