Review on 🧱 Sashco Pre Caulking Closed Backer Length: Achieve Seamless and Professional Caulking Results by David Bott

This size is ideal for connecting between the garage floor and driveway. The seam was about 1 inch wide, and the 1 and 1/4 gauge provided enough tension to hold the Zikaflex support rod securely. I also used the leftover support rod to fill in a new garage door rubber bottom seal, which worked well too.
