Safety Disc for Mitchell Plate to Modulus-X® (3/8")

The Safety Disc belongs to the Mitchell Plate for Modulus-X®. That plate rests on the frame and is otherwise held only by the Mitchell nut of whatever is mounted on top — the disc is the 3/8" part that secures it in its own right. Machined from high-grade aluminium and hard-anodized in Germany by Grip Factory Munich.
