This is an EFC brand AX400 expansion fitting for 4" rigid conduit. It has 4 inches of internal movement. This is equal to an Appleton XJ400-4 and similar to a Crouse Hinds XJ104. I also have bonding jumpers available.
I also have most other sizes in my store. Check my feedback and buy with confidence. We have been in business for 20+ years. As with all my listings, your satisfaction is guaranteed. I can ship same day ups if the order is received before 3:00 pm central. Check my store for more fittings or contact me for items not listed.
