  • Just What I Needed
Color: Silver Size: 3.9ft x 5/16" thick
This, along with a high security padlock, keeps my portable generator secure on tmmy travel trailer.

  • Great for added security out doors
Color: Silver Size: 3.9ft x 5/16" thick
I purchased this for my church side gate after someone cut our old chain to steal our church snow thrower. This chain is much denser and more difficult to cut.

  • Good Quality
Color: Silver Size: 5.0ft x 1/4" thick
It works quite well as a security chain and has kept people out of a sectioned off part of my store I work at.

  • Exactly what I needed
Color: Silver Size: 3.9ft x 5/16" thick
No box stores near me carry hardened chain. I confirmed the integrity of the chain with 24 inch bolt cutters (the largest I have). As a control, I tried and succeeded at cutting the chain I was previously using which was roughly equivalent in size --normal galvanized variety.
