Suspended unistrut support

[Fcollins]

I couldn't find this in the code book, but if you are hanging 20 foot pieces of unistrut in a continuous 60 foot run suspended from 3/8 all thread, what is the maximum spacing allowed between all thread hangers. The unistrut is support track lighting.

Check the design section of the Unistrut manual. You will need to calculate the load on the Unistrut to determine the number and spacing of the anchors you use, which will also depend on whether you are attaching to a concrete deck, corrugated metal deck, bar joists, "Z" or "C" purlin, etc.

This will not be in a code book, as there are numerous circumstances that must be accounted for. One major one is the load, with the attachment being just as important.
