Looking to add an additional device holder to your RubiGrid® dash mount or maybe you're looking for a smaller standalone mounting base for a more custom installation? Our lineup of AMPS balls are just what you're looking for! Each AMPS Plate and 20mm Ball Joint Assembly comes with Heavy Duty Bolts, washers and Nylon Locking Nuts so you get everything required for a rock solid installation. The ball size is 20mm and is compatible with any of our standard Carbon Fiber + Kevlar Mounting Arms with 20mm connector ends and our GoPro Mount.
