Durable, clean finish: surface treated with antioxidation technology for a smooth, attractive appearance that resists corrosion and wear. Stable, flexible positioning: supports 360 degree horizontal rotation and 180 degree angle adjustment via the ball head, so you can aim the projector precisely. Secure angle lock: use the antiwire adjustment fixed valve to lock the ball head at the chosen angle and prevent drift. Compact and retractable: easy to assemble and designed to take up minimal space when not in use. When you need more reach, pull out the inner rod, rotate the telescopic fixed valve clockwise, and tighten to secure the extension. Wide compatibility and rated capacity: suitable for projector wall mount and ceiling mount installations; fits most projectors and holds up to 3.6 kg / 8 lbs. Key attributes Function: 360 degree horizontal rotation; 180 degree ballhead angle adjustment; telescopic extension with locking valve. Compatibility: designed for both wall and ceiling projector mounting; compatible with most projector models. Performance: stable load capacity of 3.6 kg / 8 lbs; antioxidation surface treatment for longterm appearance and reliability. Installation: straightforward assembly with manual telescopic adjustment and valve tightening for final positioning. Practical use scenarios Home theater: ceilingmount a compact projector to the center of the room, then rotate and tilt the projector for exact screen alignment. Classroom or small meeting room: wallmount the projector and finetune the horizontal rotation and ballhead angle to avoid keystone and ensure clear projection for all seats. Temporary AV setups: use the retractable feature to stow the mount when not in use and quickly extend and lock it when setting up presentations or movie nights. What this solves Eliminates constant reaiming by providing a secure, lockable ballhead and rotation range. Protects the mount finish and appearance with antioxidation treatment, reducing visible wear in use environments. Saves space when not in use through a compact, retractable design while still allowing ondemand extension and secure locking. Includes clear, mechanical controls only — pull to extend, rotate the telescopic fixed valve clockwise to lock, and tighten the antiwire adjustment fixed valve to secure angle.
