Cone adapters
These connecting pieces have a cone adapter and are combined with a connecting element with a cone mount. This creates a rotatable connection that is fixed in place with three grub screws. The majority of ZEISS connecting elements have built-in taper adapters (CA), which can be inserted directly into a swivel mount or the taper mount (CR) of an extension. This means that cubes, end angles, star, L and T elements can be aligned very easily and quickly. Relative to using a cube and screw combination, the cone mount provides a better method to align a styli to the correct angle.
