### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Far better than the old foam tape
  

*by T***. on Reviewed in the United States on January 13, 2024*

This rubber cap seal yields a far better seal than my old foam tape seal.  I would recommend to anyone.  Just as easy to install than the old foam tape.  Great product.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Sealed perfectly
  

*by M***E on Reviewed in the United States on April 1, 2024*

Worked well, better than others I've tried.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good seal for my ARE topper
  

*by K***H on Reviewed in the United States on March 7, 2021*

I was impressed at the thickness and apparent quality. The adhesive was much better than I had expected after reading other reviews. I purchased some weatherstripping adhesive but didn’t need it.The provided instructions were good and easy to follow.This seal is much thicker than the original foam gasket that came with my ARE topper. My topper now sits approximately 1/4” higher than it used to but the seal looks much more substantial.I had plenty of leftover seal due to my 5’ bed on my Chevy Colorado.If you buy this seal you’ll see the quality right away. This seal is much better than that foam junk.
