Despite its lightweight aluminum construction (5.1 lbs.), the SS238B tripod stand safely supports up to 70 lbs. Its dual locking height adjustment mechanism clamps the inner 1-3/8" tube, while securing it via a permanently attached pin that slips through pre-punched holes.
The speaker adapter plate provided allows stand mounting of most loudspeaker brands. Sockets built into Yamaha's Club IV cabinets make them "speaker stand ready." Also works great with the new StagePas System.
