AMPS Compatible 20mm Ball with Metal Mounting Plate

Each AMPS Plate and 20mm Ball Joint Assembly comes with Heavy Duty Bolts and Nylon Locking Nuts so you get everything required for a rock solid installation.

Hole locations 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 ball size is 20mm and is compatible with our Carbon Fiber + Kevlar Mounting Arms and our GoPro Mount.

**PATENT PENDING**

2-HOLE vs 4-HOLE AMPS BALLS

Choose between our rectangular 4-Hole plate, 2-Hole plate or Mini 2-Hole plate depending on your needs.

4-holes AMPS balls are recommended for maximum stability with phone and tablet holders.

2-hole AMPS mounts are suitable for lightweight action cameras, other lightweight devices or certain narrow RubiGrid® dash mounts such as our 2022+ GMC/Chevy RubiGrid® Dash Mount and our 2016-2023 Toyota Tacoma RubiGrid® Dash Mount.

The 2-Hole Mini is perfect for squeezing in an extra device when space is limited. The 2-Hole Mini is compatible with the Magnetic Mic utilizing their supplied hardware.

BUILD QUALITY & MATERIALS

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.

RUBIGRID® COMPATIBILITY

These plate and ball assemblies are fully compatible with our RubiGrid® Platform Base for the Jeep Wrangler JL and Gladiator, RAM Truck RubiGrid®, RubiGrid® for GMC Sierra & Chevrolet Silverado as well as our Ford F-Series Mounts.
