Before Moving a Hanger or Brace

Use before changing rods, straps, trapeze, anchors, seismic braces, or support layout.

A hanger/brace is in the way, missing, too short, misaligned, or conflicts with another trade.

Stop if

• Ask whenever support spacing, anchor type, seismic brace, structural attachment, load path, or trapeze arrangement changes.

Watch out

• Do not remove a support because it is inconvenient.
• Do not move seismic bracing casually.
• Do not use random anchors/hardware.
• Do not leave duct unsupported while solving another conflict.

Check

• Anchor point
• Rod/strap/trapeze
• Duct being supported
• Conflict causing move

Steps

• Treat supports and seismic bracing as engineered/approved until told otherwise.
• Identify whether it is a normal hanger, trapeze, brace, seismic restraint, equipment support, or temporary support.
• Check approved support drawing/detail if available.
• Check nearby duct weight, insulation, equipment, damper/access, and connection load.
• Measure what changed and why it does not work.
• Take photos showing the whole support path from anchor to duct.
• Ask before moving anchor points, deleting supports, changing brace angle, or increasing spacing.
