Baader 2" Clicklock Adapter Features:
The Baader ClickLock (1¼" / 2") is a precisely fitting, very massive eyepiece clamp without clamping screws (!). Inserted eyepieces, CCD cameras and similar accessories are securely held in place, locked against rotation and won't be scratched in any way! With a small turn of 20°, each eyepiece is firmly clamped. You will never have to handle small locking screws again – instead, just rotate the top of the eyepiece clamp for a few degrees, and the eyepiece will be firmly fixed. This is also no problem with gloves on!
Our various ClickLock clamps are made of seven precision-machined components which provide a highly effective retention mechanism that securely holds any 1¼" or 2" eyepiece. The clamp is very expensive to assemble, the price therefore initially may appear high for "nothing more than" a clamping device. But if you think about the comfort, precision and stability, it's well worth the money.
You do not have to tighten the ClickLock clamps with brutal force, because the mechanical principle comes from professional mechanical engineering. This is how the tool holder in modern CNC milling centers works. Clever use of leverage multiplies the torque. The inserted object is held on three sides similar to a quick-action chuck and can therefore no longer carry out any tilting movements.
Example of switching a standard 2" clamp to 2" ClickLock
We have tested the effectivity and stability of the ClickLock mechanism for many years with the 1¼" ClickLock clamp.
The 2" ClickLock system is designed to be much more mechanically solid.
With the 2" Clicklock clamp, you can also convert e.g. your 2" Maxbright mirror (or the 2" universal prism) to the Clicklock system, simply unscrew the old 2" clamp and screw on the new 2" Clicklock clamp.
