OK guys I need some of your expertese. I have several runs of MC cable with 4-5ookcmil conductors running up a shaft in cable tray 6 storys at a time. What is the best method of supporting the MC cable? Do they make a type of strain relief for this type of application?

What about something like Panduit MS4X625X15-LS ? http://www.panduiteeg.com/catalogs/en/ww101n16j-nl/pdfs/sa101n16j-nl.pdf

One of the {if not the original?} producers of a wide variety of basket grips is Hubbell/Kellems http://www.hubbell-wiring.com/tools/tools.htm select “4. Kellems Mesh”

Don’t forget the infinitely handy “Cush-a-Clamp” http://www.cushaclamp.com/clamp.html or the very hip, truly hard-core “Porce-a-Clamp” http://www.cushaclamp.com/pclamp.html
