Bulletpoint AMPS Compatible 20mm Ball

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.

4-holes AMPS balls are recommended for maximum stability with phone and tablet holders. Hole locations for our 4-hole ball are in the standard AMPS pattern of 30mm x 38mm (1.181” x 1.496”) so this will mount to anything with the AMPS hole configuration. The base is made from precision laser-cut metal and features a thin rubber strip to help absorb and reduce unwanted vibrations as well as prevent scratching with the mounting surface. The 20mm machined ball is also made from metal and features grooves to help provide additional friction and grip so your device won't spin or move.
