Material: metal clamp block and metal nut for durability
Function: secures column sections and provides adjustable clamping force
Finish: corrosion-resistant surface treatment for extended use in studio environments
How to use
To replace the clamp block and nut, lower the column and remove any attachments or loads. Disassemble the existing clamping assembly by loosening and removing the worn nut and block, then fit the replacement clamp block into the same orientation as the original. Thread the supplied nut onto the shaft and tighten to the required holding torque, testing the column under typical load conditions to confirm secure operation. Reinstall accessories and verify smooth height adjustment and firm locking before normal use.
Usage recommendations
Inspect clamping surfaces regularly for wear or contamination and lubricate screw threads lightly if motion becomes stiff; avoid over-tightening to prevent thread damage. Replace both clamp block and nut together when significant wear is present to ensure consistent clamping performance.
