The one I was thinking of is called a knockout plug... but I could only 
find up to 2".. check out the knockout seal on page 70-4 of McMaster Carr ...

  the 2 1/2" model seems just what the Dr. ordered... I would paint it with 
matching /or contrasting color and install.....looks like they are $3.22 
each and probably some shipping if they don't have an outlet near you... 
You should check your electrician buddies for one on the truck ..... If no 
luck, I should be able to turn something on the lathe that would do the job...
