The hardware I purchased was the top mount hardware. The hardware seems to be good quality except for the soft-close mechanism. It actually doesn’t seem to work with the top mount hardware. Because the door is a set distance away from the track, the mechanism attached to the top of the door isn’t high enough to trigger the soft close mechanism attached to the track. In addition the instructions are not clear and light on detail. It would be helpful if there were more pictures or even a video that could be accessed online that demonstrates the step.
