🔎 Quick Answer: A 2-pack of Unistrut-compatible #4872 trolley intermediate support brackets provides mid-span support for strut channel used in trolley, festoon and light conveyor systems. They bolt into standard strut channel to carry load and keep long runs straight and properly spaced.
What They Do
On long strut-channel runs, intermediate supports sit between end anchors to share the load, prevent sag and keep the channel aligned for trolleys to roll smoothly. The #4872 pattern bolts into standard strut using channel nuts.

Where They’re Used
- Mid-span support on long strut runs
- Festoon cable trolley systems
- Light material-handling / conveyor tracks
- Workshop and industrial framing
- Anywhere a strut run needs anti-sag support
Installation Tips
- 1
Plan spacingSpace intermediate supports per the load and span (don’t over-span).
- 2
Insert channel nutsDrop spring nuts into the strut at each bracket point.
- 3
Bolt the bracketFasten the #4872 bracket and torque evenly.
- 4
Check alignmentConfirm the run is straight and the trolley rolls freely.
⚠️ Match bracket and hardware to your strut size and rated load — under-supporting a run causes sag and binding.
Frequently Asked Questions
What are intermediate support brackets for?
They provide mid-span support on long strut-channel runs to carry load, prevent sag, and keep the channel aligned so trolleys roll smoothly.
Are these compatible with standard Unistrut?
Yes — #4872-style brackets bolt into standard Unistrut-compatible strut channel using channel (spring) nuts. Confirm your channel size and load rating.
How far apart should supports be spaced?
Spacing depends on the load and span. Follow the strut manufacturer’s load tables and don’t over-span — add more intermediate supports for heavier loads.
Building a Strut Trolley Run?
Use #4872 intermediate brackets to support long strut runs, space them for the load, bolt them with channel nuts, and check the run is straight and free-rolling.
