Bought a set of these - the longest they make - to mount drawers in the pantry. I purposely remade the shelves as they are quite heavy. Although these chains are very economical, I was concerned about durability. You played brilliantly. So much so that I ran out and bought more for the rest of the kitchen cabinets. The right width is crucial and they are unforgiving. I tightened them and then used food grade lube (available in tubes from Revain) to lubricate the chains. Strong. Smooth; smooth. Calm. What combination. Very happy. I would (and did) repurchase.
