This aluminium-plastic socket tray is of very good quality and a great way to organize a small set of sockets. The socket holders can be removed by removing one of the side panels and made to order to suit the number of sockets you have. The anodized finish of the rails is very nice and the plastic used is high quality with metal balls to hold the sockets in place. . I use this in a tool box, but you can wall mount it or just put it on a workbench. Makes it easy to see when a socket is missing and works with all 1/4", 3/8" and 1/2" sockets. I use this for hex and torx sockets, they work great and even those larger sockets stay securely in place Good quality product very happy with this socket organizer.
