The Soft closing stays are for applications where the door that the stay is connected to is either opening or closing in a downward motion and there is a fear of the lid slamming shut or open when being opened or closed. The stay gets rid of this risk by slowly lowering the door open or shut by use of a dampening mechanism. Each of the stays has a maximum load bearing that it will be able to support and still open or close the door slowly and carefully, if the weight of the door exceeds this maximum load then the stay will not work to its full potential and the lid could slam.
