The Sonor DK-MK Key is slotted on one side and square on the other. The perfect tool for German older model slotted and current square rod bolts of all drum kits of today. A must for anyone with an SQ2 Sonor Kit with slotted tension rods!
Slotted end does not fit Sonor Delite Square Badge, Phonic, Phonic Plus or Designer slotted tension rods.
