Review on Optimized Double Action Spring - Rok Hardware by Adam Nelson

For $$ this double acting hinge is hard to beat. I use them for saloon doors, they are easy to install and adjust and work well. The included screws also fit, which is unusual as the included screws tend to be very cheap, easy to remove, and difficult to turn. Be sure to turn the hinges in the direction indicated in the instructions and they work fine. The only reason I didn't give this 5 stars is the workmanship. There is nothing "bad" in it, just not as good and better quality. However, I felt I got a little more than what I paid for as these hinges cost more than triple when bought locally.
