Running conduit from an old rectangular 2 x 3 exterior box?

Question

I have an old 2” x 3” rectangular recessed electrical box recessed in aluminum siding, which was standard back in 1972 when my home was built.

I am trying to figure out how I can use this box as a source to run conduit from it to a new outdoor light receptacle several feet above it.

Is there an extension box made for these smaller old boxes that I could attach to it to run the conduit to the new box 2 feet above?

If not how would you recommend accomplishing what I’m trying to do ?? Thanks for your help

Answer 1

Unscrew the light fixture on the cover of the box.

Screw in your conduit fitting.
