Pancake Box Help

Hi all,

Newbie beginner question (no laughter pls!)...Using pancake boxes for the first time as I came across a stud (3/4 inch from drywall) when moving a light receptacle to it's new location. As it's not plastic, I understand I need a 'connector' to attach the romex to the metal box? How do you then get the pancake box flush to the stud (and your drywall for that matter), with the connector sticking out back? Also I'm not use to the clamps on the pancake box, can someone explain how or what I'm fastening to that?

Thanks in advance

Got a picture of what your talking about?
Any connectors should be in the top or bottom of the box not out the back in most cases.
Sure your using the right connectors?

Normally the box can be rotated so that at least one of the knockout is not over the stud. You do not need to use the center hole.

As far as the connector, it depends on the style you are using. If it has a locknut, the locknut goes on the inside of the box.

4" pancake boxes can be a real pain in the ass when it comes to box fill, I generally just use a 4" hole saw and install a 4" octagon 1.5" deep box....
