Check the listing for details. K&M Speaker Stand With Ring Lock. Condition: New. Listed at 232.99 USD. The K&M 21467 Speaker Stand With Ring Lock is a strong and lightweight stand made from aluminum. It uses a special mandrel system called "ring lock" that keeps your speaker tight and secure without shaking. Instead of the speaker rattling or falling, plastic splints hold everything steady and cut down on buzzing. The spring-loaded bolt and locking screw make it simple to raise or lower the stand, so you get the right height every time. With tube legs, double foot struts, and big rubber ends, the base stays balanced, even with heavy speakers. You can fold the unit for easy storage, and it fits most standard speaker sizes. The K&M gear's ring lock fits speakers with poles from about 1-3/8" to 1-1/2" wide. It can hold up to 110 pounds, which is great for big events or small gigs.
