DW Hardware Workshop DWCP5002AD4 Delta Iii Double Accelerator PedalThe DWCP5002AD4 Delta III Double Accelerator Pedal with Carrying Bag from DW Drums is an improved and updated version of DW's earlier double bass drum pedal. The Tri Pivot Toe Clamp has increased gripping strength, providing a stronger connection between the drummer and his kick drum. Three independent 360 degree, rotating rubber pads firmly pinch almost any diameter and thickness bass drum counter hoop from the top and the bottom, with zero slippage.
