This review is of JCK's professional quality aluminum outlet tray in multiple sizes (three rails). I have a few loose heads that I've accumulated over the years that are just floating around in my toolbox drawers, so I ordered it when I saw this. I was expecting it to be something cheap and flimsy, but it turned out very well. I put it open in the drawer but I like that it has mounting holes. Each color-coded bar fits different socket sizes: 1/4", 3/8", and 1/2". They don't interfere with the outlets on the center 3/8" orange rail. The sockets hold in place very well and spot. In addition, you can rotate and move sockets. Made in Taiwan. Quality spout cup and you will justify your money.
