The standard 30mm cage uses four Ø6mm cage rods on 30mm centers to define the optical axis and is best suited for Ø1in (Ø25mm) optics while the 60mm cage system uses Ø6mm cage rods on 60mm centers and is better suited for Ø2in (Ø50mm) optics.

Base Lab Tools continues to expand our cage system offering and is always willing to help you customize your setup.
