M-D Building Products 71464 Backer Rod For Gaps and Joints, 3/8-by-20 Feet, Gray

Great for posting my Dobermans ears thanks x

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

Worked great to fill gap between wall and floor. But it is not a 2-pack as the description implies, just one piece.

Good product

So I've been looking around for a way to fix my concrete driveway. Unfortunately the concrete expansion joints have separated and have made a pretty big gap. After much research I found that I should use a backer rod to lay in the expansion joints and than use a self leveling chalk to seal it in. This will prevent any additional water from eroding the base material under the concrete. I needed a couple different sizes as the width of the expansion joints was different as you went up the length of the driveway. I found what I needed. The M-D Building Products Backer Rod. I bought both a 1/4 and 1/2 sizes. I like to tell people about my shopping experiences in this case I'll cut and paste this same review for both the 1/4 and 1/2 sizes I received (no big differences in these). Both the 1/4 and 1/2 inch arrived on time. They were packaged very well. Super light as you can imagine. The backer rod is like a foam material. It fit well into the expansion joints. A nice snug fit. This is exactly what I was looking for. Otherwise with as wide and deep as these expansion joints have gotten it would have taken a lot of self leveling chalk to fill them in. The material cut really easy. I use my utility knife but an ordinary pair of scissors would have worked just fine. I was happy with the quality. I felt confident when install it in the expansion joints that it would hold up just fine and do the job.

Had a small gap in my front door threshold after one of our animals ripped up the material that was originally in the gap.After reading many reviews for this product, gave it a shot. It was just what I needed! Super easy to use: measure, cut, install. Fits perfectly in the gap. No need to worry about dirt, bugs, and other debris getting in the gap.Great value too, as the 20ft bag was only about $3.00, with plenty left over if I need to replace it again.Highly recommend.
