If you would like to be able to see what is inside at a glance, using a pane of glass with a metal frame you can attach hinges for a door. An easier way of doing this, is to find a door that will fit your cabinet at a local hardware store. Easier yet if you do not need the glass, is to take another pieced of sheet metal with the edges and corners well sanded attach some hinges and voila! You have a door that opens and closes easily. If you are using your new metal storage cabinet to safely guard your expensive tools, with a bit more work, you can attach a padlock to it.
