I have an old 2” x 3” rectangular recessed electrical box recessed in aluminum siding, enter image description here 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

Unscrew the light fixture on the cover of the box.

Screw in your conduit fitting.
