Before you start

  • Use the exact manufacturer system, approved submittal, load table, anchor type, cable size, bracket, locking device, installation tool, and attachment method for the project. Do not mix components or guess a working load.
  • Confirm the exact fire-rated support system, tested or listed assembly, required fire-resistance period, cable, anchors, brackets, spacing, load, and permitted substrate.
  • Obtain the current tested or listed installation instructions.
  • Verify every component belongs to the same fire-rated system.
  • Inspect labels and components before installation.

Tools and materials

Exact listed fire-rated cable-support components, approved anchors and brackets, installation tools, identification labels, level, tape, lift, and the current tested/listed assembly instructions.

Lay it out

  1. Lay out supports exactly as the approved fire-rated assembly requires.
  2. Keep component spacing and attachment locations within the listed limits.
  3. Coordinate fire-rated support with penetrations, enclosures, and service access.

Set and support it

  1. Install only the listed anchors, brackets, cables, locks, and retention devices.
  2. Do not mix standard cable-support parts into the fire-rated system.
  3. Keep labels and inspection points visible.

Make the connection

  1. 1

    Verify the tested or listed assembly and substrate.

  2. 2

    Install the specified anchor and bracket.

  3. 3

    Install the exact cable and locking components.

  4. 4

    Set the supported service at the required elevation.

  5. 5

    Complete all retention and identification features.

  6. 6

    Document the installation before concealment.

  7. 7

    Complete required inspection.

Check the install

  • Every component matches the tested or listed fire-rated assembly.
  • Spacing, substrate, load, and attachment match the approved detail.
  • Labels and documentation are complete.
  • No mixed or substituted component is present.
  • The system remains accessible for inspection.

Common mistakes

  • Assuming a standard cable hanger becomes fire-rated when used with firestop.
  • Mixing ordinary locks or anchors into the system.
  • Changing spacing in the field.
  • Covering labels before inspection.

Stop and ask

Stop if the tested/listed assembly, fire rating, substrate, spacing, component identity, or manufacturer instructions are unavailable or do not match the field condition.
