- Hand Crank With Push-Button System Prevents Uncontrolled Downward Movement
- Locking Screw Adds Secondary Safety Retention Beyond The Crank Mechanism
- M20 Threaded Bolt Ensures Zero Backlash And Absolute Vertical Positioning
- Two-Piece Folding Design Simplifies Transport And Storage Between Events
- Steel Construction Supports Heavy Passive Or Powered Enclosures Reliably
The K&M 21339 is a two-piece folding distance rod engineered for production environments where absolute vertical positioning and zero backlash are non-negotiable. Unlike standard speaker stands that rely on friction collars or basic pin locks, this rod integrates an M20 threaded bolt specifically matched to the K&M connector plate 24116, ensuring a fixed, repeatable vertical fit every time it is deployed. The hand crank height adjustment paired with a push-button safety system gives the operator controlled, deliberate movement through the 914 to 1504 mm range, eliminating the uncontrolled drop risk present in quick-release or cam-lever designs.
With a rated load capacity of 50 kg and a steel construction throughout, the 21339 is suited for installed AV environments, touring rigs, and rental inventory where a powered or heavy passive enclosure must be rigged safely at mid to high trim heights. The locking screw provides a secondary retention point beyond the crank mechanism, making it appropriate for applications where vibration or extended set times are a concern. Its 35 mm diameter tube end maintains compatibility with standard speaker stand hardware, broadening integration options across mixed-inventory production setups.
