This stuff made posting my doberman's ears a piece of cake. It's soft enough that I don't have to worry about it hurting his ears but sturdy enough that his ears stand up nice and straight along with a sturdy bridge in the middle. Great product if your posting your doberman's ears at home!

I had to fill a small space in my window frame and this worked great. Easy to cut and just push it in any crack or space. Very easy.

It worked well for filling a large crack in my concrete walkway so I could top it off with the liquid crack filler.

I’ve been using very thin backer rod for posting my dog’s ears, and it’s been a fantastic solution! It’s lightweight, flexible, and provides just the right amount of support without causing any discomfort. It’s easy to cut to size and stays in place securely. Plus, it’s gentle on the ears and works perfectly with sports tape. Highly recommend for anyone looking for a reliable and comfortable ear-posting method!

We needed it to put between patio and house where the product used before had basically dissinegrated. We noticed dampness on the diner block wall. Since installing no issues. Wished it would have come a little larger in diameter but we made it work.

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.
