Review on 🔗 Ultra Hardware 30.5-Inch Chain Crash by Rick Everett

I have an industrial steel door so I used other screws but assembly is pretty easy. Make sure the door bracket is set low enough not to interfere with the door seal when the door is closed. I drew a line through the middle of the chain and used equal lengths of each end of the door frame and the door with the door open as far as I wanted it to open. Each installation will be slightly different, just make sure you erase everything. Love the dual springs, chain size and chain guard. I liked it so much that I bought a second one for my other building.
