To me those are known as Kellum Grips. I don't think NEC requires those
however for this application. Simply "Strain Relief" fittings are what the
OP needs.

Borg, etc. have 1/2" romex like connectors with rubber gripping sleeves in
them. Naturally I forget the name. I'm thinking this is just for the drop,
with the feeds in Romex?
There are Kellums grips if you want to take the weight back to a ceiling
hook.

314.23(H) Pendant Boxes. An enclosure supported by a pendant shall comply with
314.23(H)(1) or (2).
(1) Flexible Cord. A box shall be supported from a multiconductor cord or cable
in an approved manner that protects the conductors against strain, such as a
strain-relief connector threaded into a box with a hub.
I can't recall if it is SO or SJ but the 14 and 12 guage have chinese
fingers you can get at a good electrical house.

His description is not quite correct. My understanding is that like
the chinese fingers I got at the 4th of July carnivals, you slide the
SO/SJ cord in and it does not want to come back out. Of course you
have to get the thick cord for it to grip.

Are you referring to Twist-Lok? I don't know what the code says about it.
