Recommendations for filling long cavity with limited access.

Hello,

There is an un-insulated cavity where my garage addition attaches to the house. It runs the height of the wall and is about 4" deep by 4" wide.

Visualize a very long box. Looking at the top of the box, it's 4" x 4". The box is around 9' long.
Along the edge of the "box" there is a slit about 1/2".
I could easily fit the tube of canned spray foam in there, but I think I'd use a huge amount of the foam.
The slit is not quite large enough to allow me to stuff fiberglass or Roxul insulation in there.
I was wondering if cellulose insulation would work. Is there a "project sized" kit available for cellulose?

Any suggestions?

Thanks in advance.

Got a picture of the outside in that area?
Trying to picture why it's even there and why it was not dealt with as the outside walls where being done.

I stick another piece of tubing over the spray can tube. Slide the tube to the back of the cavity and start foaming as you slowly pull the tube out. Make sure to wear rubber gloves and have a garbage can ready to throw the tube in once you're done.

The only machines I have ever seen are the size of a small refrigerator.

Any way one of the studs could be cut out filled then replaced?

Thanks @joecaption. @Pilot Dane, and @Marq1

@joecation, Hopefully the attached picture will clarify the situation.

@Pilot Dane, Good suggestion re: adding a tube.

@Marq1, I suppose it is possible to remove the stud. I would need to chase down the electrical wire that runs through it.
