Much stronger than the ones in the kit I've replaced. They're broken. The screw holes did not match, but this mount is adjustable. And no need for precision. The drawers fit better than the old ones, but that may also be due to the fact that I screwed in the screws very carefully. The only criticism is that the supplied screws are too short. I have used longer ones. This is the only reason for the 4 star rating. This is a good product.
