K&M Stands 21322.000.55 Extension for Light Stands

Extended Reach for Precise Speaker and Lighting Placement
The K&M 21322.000.55 Extension Tube is a steel-built 300 mm adapter designed for use with speaker and lighting stands featuring M10 threaded bushings. Whether you're running a compact column speaker or a lightweight lighting fixture, this extension gives you the additional vertical height you need without compromising stability. It's a simple but powerful tool for achieving optimal projection and audience coverage in a variety of live event or installation setups.

Compatible with M10 Threaded Mounts and Stands
Fitted with M10 threads on both ends—female and male—the extension tube integrates seamlessly with popular crank stands like the K&M 21300. This dual-thread design ensures flexible positioning and fast installation when you need extra vertical clearance. It's ideal for adapting gear that sits lower than you'd like or for setups where direct audience line-of-sight is critical.

Ideal for Lightweight Column Speaker Systems
The 300 mm height makes this extension particularly useful for slim column-style speakers that benefit from a slight height boost for better acoustic coverage. The 35 mm outer diameter matches standard speaker pole dimensions, making this accessory compatible with a wide range of systems from various pro audio brands.

Steel Construction Delivers Long-Term Durability
Manufactured from robust steel, this extension tube is built to last through the rigors of frequent use in live sound, corporate AV, and installation environments. Its black finish resists scuffs and scratches, while the solid build ensures it stays reliable no matter how many times it's loaded in and out of a gig.

Lightweight and Easy to Transport
Weighing in at just 0.7 kg, this accessory won't add bulk to your road case or setup routine. Its compact dimensions make it easy to carry as a spare or pack multiples for large-scale systems that require matched extension across speaker arrays or lighting trusses.

A Must-Have for Touring Techs and Installers
AV professionals working on stages, conference venues, or installations will find this extension tube invaluable when working with speaker stacks or lighting where precise height control is essential. It offers one of the most effective ways to fine-tune positioning without changing your entire stand system.
