RAM Mounts Ball Adapter with AMPS Plate (RAM-347U) is a 43 × 51 mm (1.69 × 2") rectangular aluminium plate with a C-size 1.5" (38 mm) rubber ball that fits any RAM C-size double socket arm. Its four pre-drilled holes follow the universal AMPS pattern (30 × 38 mm), so it screws straight onto RAM holders and cradles with an AMPS pattern or onto any flat surface. The ball sits at a right angle to the plate. Powder-coated marine-grade aluminium keeps it durable in vehicles, on equipment and outdoors.
