I've had some shoe racks in use, this is the first pull. I was skeptical at first as to whether the mechanism works and also carries the weight. But I can only report good: - The structure: simple, well described and dealt with quickly - The glands are not metal to metal, but have a plastic cap on the extraction rod; thereby the screws tighten automatically, very good solution. - Stacking: quick and easy, good and solid connector. - Adjust the width: smooth running of the bars, fast and accurate fitting in alcoves and corners. Conclusion: Beat at this price, good quality will, order this item again if necessary
