These rails are not top quality but do the job. I used them to make a pull out shelf for my desk. I have to pull quite hard to make the shelf slide, but my shelf doesn't have a handle. If you're using them for a drawer, that's probably less of a problem since you'll have a handle. The first set I received was defective (one of them had a broken plastic clasp) but the second pair was fine. If I could find a better quality set of drawer slides I would buy them, but these were the only 20" soft close slides I could find.
