"We use these screws in my research lab here at Stanford University. Our research field involves manipulating single atoms and molecules. But the connection with your rack mount thumb screws is that we use racks full of commercial and custom built electronics for our control systems, and we are constantly reconfiguring equipment to adapt to new experiments and to test new strategies. These screws have been fantastic in keeping things running smoothly in the lab on a day-to-day basis, and also quite helpful when we have to install and move around heavier pieces of rack-mount equipment."

" My position at Cisco requires that I move many pieces of equipment almost every day. The Rack Release system allows me the freedom of mobility as well as the convenience of rack mounting equipment that is not in use. The design of the mounting screws as well as the ease of assembly allow for quick installation and tear down (often with nothing more than my fingers). You have made my job MUCH easier. Thanks for a great product!"
