Toolbox...any that are 'quick release'?

I've seen the Stanley plastic box that can come out of the bed...fits in on rails or something like that.

Does anyone make a traditional style toolbox that can be quickly removed if you need to use the whole bed? Maybe a bracket that attaches to the rails, with a quick release on the inside of the box to remove it from the bracket?

 

I just use bolt hooks that thread up through the tool box and hook the bed rail, there easy to take on and off and require no holes...
