Light and compact, the On-Stage Stands SSAS7000B is an excellent choice for light-duty work in bars, clubs, hotels, churches and other venues where small portable PA's are routinely used. An ergonomic knob adjusts stand height from 27" to 46", while the folding tripod base maintains a low center of gravity, allowing exceptional stability when used with speakers up to 60 lbs. in weight. The 1-3/8" upper shaft is compatible with virtually all current pole-mount speakers, and now includes a locking pin & preset height adjustment holes.
