The SS7748 Airlift Speaker Pole from On-Stage Stands is an intelligently designed pole that makes getting your speaker placed above your subwoofer a breeze. With a 45 lb. internal gas cylinder pneumatic lift assist and a 100 lb. weight capacity, the SS7748 has all-steel shafts and telescopes from 36.5" to 60", letting you get perfect placement height for your gig. This unique pole also includes a first-to-market removable M20 threaded lug making it compatible with just about any sub on the market. There is also a standard 13/8" cup fitting, so you can pick and choose whichever works best for your particular setup.  We found the Airlift system a real game-changer. With a simple twist of the clutch knob, the system does most of the lifting for you!
