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
- Lay out supports exactly as the approved fire-rated assembly requires.
- Keep component spacing and attachment locations within the listed limits.
- Coordinate fire-rated support with penetrations, enclosures, and service access.
Set and support it
- Install only the listed anchors, brackets, cables, locks, and retention devices.
- Do not mix standard cable-support parts into the fire-rated system.
- Keep labels and inspection points visible.

- 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.
