The G4825 Hinged Diamond Plate Bracket is another distinctive part that helps define why Gretsch is so unique in appearance. It's standard on all USA series floor toms and thanks to it's classy and low profile appearance, the G4825 is quickly becoming the "go to" for direct-to-shell mounting on rack toms. The G4825 hinge system aggressively clamps down on any 12.7mm (1/2") arm preventing potential slippage while playing your toms. It's offered as a direct-to-shell build option on custom builds and available as a Gretsch aftermarket sales part.
