Baader 2" ClickLock Clamp for 2" SC Thread (Female SCT to 2" Receptacle)

If you’re done playing “how tight is too tight?” with thumb screws, the Baader 2" ClickLock is the upgrade that makes your SCT feel like a precision instrument again. This clamp threads onto male 2" SC (SCT) threads (think Celestron C8 or Sky-Watcher Skymax-180) and gives you a rock-solid 2" accessory receptacle that locks down with a quick lever move—secure, centered, and no chewed-up barrels.

• Fits focusers/visual backs with male 2" SC (SCT) thread (commonly on SCTs and Maks)

• ClickLock clamping holds accessories on the optical axis—secure like a threaded connection, but faster

• Locks with a simple ~20° lever rotation (no knuckle-busting tightening)

• Twist-proof hold to reduce tilt and wobble with heavy 2" diagonals, eyepieces, or cameras

• No locking screws digging into your gear—designed to hold expensive accessories without scratches or marring

• Thick-walled hard bronze compression ring keeps its shape for years and clamps evenly

• Ratchet feedback provides audible/tactile confirmation—handy when you’re working in the dark

• Adjustable lever position (swap orientation via the included screw positions) so it’s comfortable for right- or left-handed setups

• Built with a mechanical clamping principle inspired by professional machine tool holders (high force, low effort)
