RAM Mounts Round Plate with Ball, C-Size, AMPS Pattern (RAM-202U) combines a C-size (1.5") overmoulded rubber ball with a 63.5 mm (2.5") round plate of powder-coated marine-grade aluminium. The plate is pre-drilled with the universal 4-hole AMPS pattern (30 × 38 mm) and a 3-hole 120° pattern (Ø 46 mm), so it works both as a drill-down base on a dashboard, console, forklift or desk and as an adapter that puts a C-size ball on any cradle or holder with an AMPS pattern. RAM also uses this plate as a component of kits such as RAM-103U-D and RAM-224-3U.
