The Tri Stand Guitar Stand safely supports 3 guitars or basses. Features innovative Hercules Auto Grab System (AGS) yokes: the arms turn in and up with the weight of your guitars to hold them securely and simply open up when you lift them off. All contact points with the instruments feature Specially Formulated Foam (SFF) rubber to protect your finish. Also features the Hand Grip Height Adjuster, which makes adjustments a breeze with a locking pin to secure the stand in place. Folding backrests flip down to support your guitars and back up for storage and transport. All Hercules stands are safe for most nitrocellulose lacquer finish guitars*. *Hercules tests for many types of nitro finish, however some guitar manufacturers change their nitro mixture often. Guitars should never be stored on a stand...always in the case.
