  • Good, but…
Color: Orange Size: 15.5"-21"
I got one to freeze up when a load was put on it—how much, I don’t know. The threaded rod froze and it took me a bit to undo it. Now the threads look compromised so it’s done. Overall, it did what I needed but just seemed to fail a little too quick for me.

Used these to permanently support a main beam in the basement. The installation couldn't have been easier. No complaints at all.
