{"product_id":"k-m-21339-000-55","title":"K\u0026M 21339 Distance Rod With Hand Crank For Connector Plate | Black","description":"\u003cp\u003eThe K\u0026amp;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\u0026amp;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.\u003c\/p\u003e\u003cp\u003eWith 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.\u003c\/p\u003e","brand":"Connolly","offers":[{"title":"Default Title","offer_id":52446167892152,"sku":"43089","price":297.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/43089_K_M-21339-Distance-Rod-With-Hand-Crank-For-Connector-Plate-_-Black_ALT01sqr.jpg?v=1790884711","url":"https:\/\/soundpro.com\/products\/k-m-21339-000-55","provider":"SoundPro","version":"1.0","type":"link"}
