The Music Store KB-4 EX is a double X stand for keyboards, synthesizers, stage pianos and electric pianos in sturdy tubular steel construction. For quick assembly and disassembly, there is a convenient release lever that locks the keyboard stand in one of seven selectable positions. The load capacity is stated at about 40 kg, which should be sufficient for most keyboard instruments. The KB-4 EX can be used with the KB-50 keyboard stand attachment to add another support level.
