Got tired of my sockets always falling out of the box and getting all mixed up. I decided I need to lock them down somehow. Did some lookin around and found these socket organizers at Sears. Push the socket on and give it a 1/4 turn and it locks em in place. The racks are magnetic, but also have holes on the end to bolt them down. I used some stainless screws to secure them to the lid. Workin great and not having any issues with them coming unlocked and falling out.

 

I also have those for my impact sockets, they work great.
