    Perfect
  

*by B***N on Reviewed in the United States on December 3, 2021*

I installed these in the upper rails of my trailer to allow me to strap things down more securely.  They were manufactured by National/Stanley and were just what I needed.  I used to have only 4 on my trailer and now have 9.  Never have had one bend.
