GU Optics's Cage Plate Stops mark the position of a cage plate, allowing it to be reliably moved and repositioned in a cage system. These clamps are 3.5 mm thick and compatible with our Ø6 mm cage rods for 30 mm and 60 mm cage systems. Utilizing a flexure design, the clamps are secured in place using a 1.5 mm hex key. They can be easily clamped onto a cage rod without removing other components.
