This is a solution for the caulking tube that has been cut farther back due to clogging or caulking large joints when it is desired to then caulk a small joint.

Obviously the front end of a desired size tube has been cut and piggy backed on to the “gusher” tube.  Since this increases length the rear of the tube needs to be cut too (best to end up with standard total length). 

I’m liking that “scotchlock cap” trick I stole from another thread.
