AMPS Compatible 20mm Ball with Metal Mounting Plate

BMS-Amps4Hole

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 are suitable for lightweight action cameras and other lightweight devices.

The 2-Hole Mini is perfect for squeezing in an extra device when space is limited.

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.

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.

Shown below are 3 of our RubiGrid® systems with the 4-Hole AMPS Plate & Ball to demonstrate what is possible.

Works on my Garmin 890

Bought this to replace the ball on my Garmin 890 mount. Easy replacement and the ball provides a solid grip.

Awesome Mounts

Got tired of years of windshield mounted items with all the circle marks they leave and all the wires hanging down the center stack. These mounts are strong, clean, and work great. I also ran 12v and USB power to the upper dash. The only issue is the padding on the bottom squeezes out a little when getting them beyond hand tight. The full install and additional pics posted on the f150gen14 forum.
