The Hercules SS710B is a lightweight, heavy-duty speaker stand with a convenient hand crank that makes it easier to hoist your speakers up to the right height. Some of today"s powered speakers are pretty heavy and require a couple of burly band members to mount them onto the speaker stands. With the Hercules SS710B, just mount the speakers onto the stand in the "down" position and crank it up to the desired height. The system allows just one person to easily raise and lower speakers or lights thanks to a revolutionary system that drives two posts simultaneously. Turn the handle clockwise for fast and effortless loading, and counterclockwise for lowering. The dual brace leg construction reinforces and strengthens without excess weight. The SS710 comes with a stand adaptor that accommodates all contemporary speaker mounting flanges.Crank operation for easy raising and lowering Holds up to 100 lbs. Folding tripod legs for east transport Aluminum tubing for lightweight strength
