What is acceptable for a "Pull Box"?
I am planning to install 3/4" PVC conduit from inside the house, to the outside. The conduit will come out of the soffit (2 foot overhang on the house) and run vertically along the block foundation. I would like access to the inside of conduit immediately after leaving the soffit so that I can install Duct seal.
I haven't been able to find anything that looks like an "inline" LB. Someone told me I should use a single gang outlet box with a full face cover as a pull box. Is this OK?

do you mean like this?
that would be a "C" condulet. (as opposed to an LB, LL, LR, N, T, or X)
just to explain some of the others:
these would be an "N", a "C", and a "T" (left to right). An X would be a 4 way and the LL and LR are variations of the LB.

Even if you can use a C conduit body as mentioned above, you may still want to consider a weatherproof device box, just in case at some time you want to add a receptacle at that point or splice to a branch conduit. I would use a 2-gang weatherproof box so you have some extra ports available at that point. If you used a one-gang box, it would just have an IN and OUT port and you'd have to add an extension ring to take off a conduit at that point.
CBs have their place, but in 3/4" they can't be used for anything except a pull box.

au contraire` AGM. Notice the 2 holes on the top of the box.
weatherproof box
and a condulet may be used for splices IF the fill calcs allow it AND the conduit body volume is durable and legibly maeked on the body by the manufacturer.

You are right, I am wrong, in principle.
But since the OP said he was using 3/4", I assumed he would want to maintain that diameter. Maybe there is a 1-gang box with more than two 3/4" ports. I don't know.
But you don't want to restrict your "through" capacity if you do decide to add a device, do you?

I actually was going to post a bit more but for some reason did not do so.
Yes, if I would ever connsider a recep at this location, I would use a 2 gang box. I get real tired of cramped j-boxes and tossing in a recep in a single gang weather proof box starts getting too tight for my likes.
but just to prove I'm right (my wife hates it when I do this but you can't slap me over the internet):

actually, I wasn't sure they did make a box with 2- 3/4" bosses on an end. I had to go and look them up.

Wow - that is exactly what I was looking for. It must be more of a specialty item - the big-box stores in my area don't seem to carry them.
I did end up using a single-gang weather proof device box. This is being used near an above-ground pool to run the wiring to the pool-pump motor. A receptacle at this time would likely not be allowed, but I guess if the pool is ever taken away it might be nice to put a receptacle there.
I mainly wanted to be sure that a device box would be technically acceptable as a pull-box. Sounds to me like you are saying it is!
Thanks for your replies!
