Question: Do two separate pieces of EMT conduit joined by a connector qualify as a "pull point"?

Background: I need to make six 90 degree turns in 2" EMT conduit to route wire for a new sub-panel which means my run is subject to NEC 2011 clause 358.26:

358.26 Bends — Number in One Run. There shall not be
more than the equivalent of four quarter bends (360 degrees
total) between pull points, for example, conduit bodies and
boxes.

enter image description here However, I cannot find anywhere that the NEC specifically defines a "pull point" other than the examples of "conduit bodies and boxes". It makes sense to me that "conduit bodies" means having two separate pieces of conduit joined with a connector (as per the connectors to the 90 degree bend in the above picture) because the conduit bodies can be separated to allow for pulling without over-stressing the wire, but I want to confirm if this is the correct interpretation.

Or, do I need a special elbow pull fitting like shown below (the picture shows smaller conduit), or are these fittings just for convenience if you later decide to pull more wire through the conduit?

EDIT: Thanks to all for your answers. I somehow overlooked the definition of conduit body in the standard:

Conduit Body. A separate portion of a conduit or tubing
system that provides access through a removable cover(s)
to the interior of the system at a junction of two or more
sections of the system or at a terminal point of the system.
Boxes such as FS and FD or larger cast or sheet metal
boxes are not classified as conduit bodies.
  • An elbow (sweep) is not a conduit body, nor a box, so it is not a pull point. If you swap out the sweep for a conduit body, then it's a pull point. Though if the conduit is already strapped in place, you'll likely need a couple nipples to fit the conduit body in place. Also mind the orientation of the conduit body, with respect to the pull direction. – Tester101 May 25 '15 at 11:59

NO! Regular couplings, those in the first image, are NOT pull points. Pull points are conduit bodies or boxes, or even those silly little elbows in the second image.

My suggestion would be to install a conduit body at strategic locations. For your installation you really only need one.

Conduit bodies:

  • Chortle - someone (I assume not you, presume the image is from elsewhere) missed the LB in your collection of conduit bodies - I see two C and two LR, One LL and one T, but no LB. – Ecnerwal May 25 '15 at 15:12
  • Another kind of conduit body is a junction box. You only need one kind of box and you can splice in it and branch off it. I like access points every 90 degrees. – Harper Jan 5 '16 at 5:59

Conduit it typically mounted and strapped so you can not readily separate the joints shown in the first picture. Pull points would mean a way to pull the with without separating the joints of the conduit themselves.

Do it right the first time and make it easy on you or anyone else who has to work on it later.
