Review on Ernst Manufacturing 8403M - 18 Blue Magnetic Socket Organizer with 1/4 Dr Twist Lock Clips by Brian Shakey

Works great, holds my 1/2" heads very securely. I often pull these sockets out of my tool box into my tool bag and take them with me on the road. The rail works just as well in a side tool pocket as it does in a tool box drawer. Keep in mind that the magnets are not strong enough to hold the slot rail to the side of the cart or tool box. However, they are strong enough to hold my 1/2" sockets upright in my toolbox when opening and closing drawers, which I believe is their intended design.
