IMPORTANT NOTE: Flipper sizes are listed based on the prism lenses in the wells. For example, a 5PD flipper will have on each side (2) 5PD 38mm Prisms (5PD + 5PD = 10PD Range) with one side being set to Base-In and the other Base-Out. So, if you want to order a 4PD range flipper, then you would get 2PD Flipper (2PD + 2PD = 4PD).
