Adam Hall Hardware 40001 Ball Corner...
Availability date: 01/01/1970
Corner based on the corner 4000, but made of 1.2 mm steel and with ball.
Like the corner 4000 this corner fits exactly to the lidmakers 6134 and 6146.
In combination with the corner 40002 it's possible to make even smaller cases stackable without the need of additional stacking feet.
