I have access to the back side of a finished wall, and would like to add some receptacles. Is there a way to use new work boxes and attach to studs rather than clamping to the drywall ?

 

Welcome to the forums.

Sure, this can be done but it involves removing much more drywall, hence the reason for the old work box which slips in the same size hole as just the box requires.

 

Is the back side unfinished? If so. yes. Pull the nails out of the boxes and reinsert them going the other way. That way the will angle towards the unfinished space and be easy to drive in.

 

Yes, backside is unfinished. Exactly what i was looking for, and pretty obvious now. Thanks!

 

You can use the type box with the long attachment bracket that runs up & down the stud instead of over it. Use screws if there's no room to swing a hammer. These are available as single or gang-able boxes.

If you can find them get the kind with the adjustable "ears" top & bottom to hold it against the drywall or use one of those bendable sheetmetal "T" thingies on the edge of the last ganged box to keep it from wiggling in the hole when you mount the switches.

 

If you have a helper have the helper hold a board over the hole on the finished side and press the box against it when you nail. That way you are sure it is flush with the finished wall.

 

Geez. Great question, Ray. Wish I'd thought to ask that.
