Based on other reviews, I bought several of these to put in each hinge to decrease the chance that it would not be strong enough to hold back door. This turned out to be completely unnecessary as one per door was more than adequate. I used the bottom hinge because this pin will look different from your other pins and it is less noticeable if installed on lowest hinge. This pin is also longer than the average hinge so you will need to use a hack saw to cut off an inch or so. But that aside it worked perfectly and looks good. Would definitely use again.
