Description
The K&M 21340 speaker pole with hand crank and Ring Lock features a patented clamping system that locks securely into your speaker instead of hanging loosely inside it. The crank lets you adjust the height steplessly between 920 and 1520 mm, even with the top already mounted. Vibration-free, stable, and set to the right height in seconds.
Features
The Ring Lock system works with an expanding mandrel that fits flanges of 35 to 37 mm, supported by movable plastic strips that take up play. At the bottom is an M20 bolt that screws straight into your sub or tripod base. The hand crank with push-button system holds the load in place and prevents the pole from dropping uncontrollably; an additional locking screw permanently locks the set height. The two-piece steel construction folds up for transport and supports up to 35 kg.

FAQ
Will this pole fit my speakers?
At the top, the Ring Lock works with any speaker flange from 35 to 37 mm, which is the standard size. At the bottom, you need an M20 thread, as found on most subwoofers and on a K&M base plate.
Can I adjust the height with the speaker mounted?
Yes, that's exactly what the hand crank is for. The push-button system holds the load in place so the pole doesn't drop. Just stay under 35 kg.
Why Ring Lock instead of just a pin?
A loose pin always leaves some play. The expanding mandrel fits tight in the flange and the plastic strips fill up the rest, so the speaker can no longer rattle or rotate.
