    Bends/Elbows

    If you have a large job with a lot of large RGS conduit(3” +) and bends I assume factory(pre fab) elbows would be the way to go instead of field bending.

    IMO, yes. That would be one heck of a bender, tho.

    It depends, you will still need a large bender for offsets and kicks. Manufactured elbows could mean that you'll save on bending but then you may need to make extra threads in the field.

    We did a job for an out of state contractor who bid factory bends, after we counted how many (20 4"pipe duct bank than up into the control tower airport) extra fitting cost, they bought a bender.

    For a large job you will need a bender. Short manufactured elbows are easier to spin on than an elbow at the end of a full length of conduit and have a shorter radius which makes the room required to spin them considerably less.

    Takes longer to bend than install pre-fab elbow so you have to look at the material cost against added time/labor hours to install pre-fab elbow.

    A pre-fab elbow is almost never the correct length which means that you will need to add some length of conduit to it. If it's less than a full length then you will need to cut and thread so you're not saving much labor. Sometimes bending the elbows is faster and cheaper.

    All I know is the guys that know how to use a bender, make those runs look like art.
