3/4' Diameter x 80' Length Backer Rod Caulk Saver Foam Backer Rod for Gaps and Joints Backing Concrete Filler

Backer rod was exacly what I was looking for. Sealed the air gaps around my new window.

As described. Did the job. Used with caulk in driveway control joints. Would purchase this product again, if needed.

You should know that it doesn’t come rolled & organized like picture shows. It’s inside a clear plastic bag that has to be cut open. Once that’s done you will have to fight it back in the bag like a disobedient drunk snake and tape the bag closed to keep it inside But it’s exactly what it says it is, works great…!

Not as dense as some I have used, but gets the job done.

Quick shipping and great price

Good product but wrong size

Seem pretty durable and was able to push it between the 2 x 6 decking spaces before we enclose

Good product for expansion join, good, but after some months, coming out
