These clips work with the hangers for the Hafele Synergy Pull-Out Pants Racks (e.g. #41257) . Black plastic clips secure pants and skirts, and allow garments to drape with zero folds. Sold singly. 2 required per hanger.
To sum it up, I would recommend guys to buy Hafele Garment Clip for Hafele Pull-Out Pants Rack at Rockler. For 1.99 it's just awesome!
