Good low cost back rod
Used this foam to seal up the concrete around my 4inch pipe for Radon System before I caulked. I stuffed this around the pipe to fill in the gap and then covered it all with high quality caulk to seal it up perfectly. It worked perfectly and is far cheaper than what i found at my Home Center. Make sure to purchase a thickness that is a little wider than your gap so it make a tight fit.

Use THESE, not spray foam
Sometimes caulking or spray foam is not appropriate for the job, and is an excellent permanent base fix prior to caulking. Creates no pressure on door and window frames

Does what it was made for
Did exactly what it was designed to do.

Works well for insulation also
Stuffs easily into door and window cracks to provide insulation in irregular sized gaps. And works well as intended caulk saver for large cracks.

Use in conjunction with hollow plastic rods (from Amazon) and lead tape to make shaft heavier after club assembly.
