Fix the unique, CWH hangers singly or in pairs and a frame is ready to hang flat and safe on the wall. Using them means that picture cord may become a thing of the past. CWH hangers hook on to almost any kind of wall fixing - picture hooks, nails, screws, gallery hooks, etc. Unlike most other hangers, they offer some sideways adjustment. They work with almost any type of wood, polymer or aluminium frame, up to around 15 kg / 32lb.
