Here we get a close up look at the studs that are in the adapter. These can be removed and you can screw the adapter into your 3.5" drive bay. This is where the innovation comes in and why I really like this product.
Remember those springs we mentioned a few pages back? It is time to put those into action.
On the back of the adapter there are two places to squeeze the adapter together and that changes the location of the studs. With the studs pulled back the adapter slides into a 3.5" form factor HDD bay without effort. This is a very cool feature and the one that sold me on the adapter.
