Stop and ask
Stop. Get direction before you touch it.
Loose or unverified brace fasteners are a stop-and-report item. Tight-looking hardware is not the same as verified hardware.
In Seismic Bracing, Sway Control & Structural Coordination, I'm looking at: Brace fasteners not tightened or inspected. What should I verify before I cut, drill, seal, cover, move, or install?
