AMPS Compatible 20mm Ball with Metal Mounting Plate

SKU BMS-Amps4Hole

Size

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.

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. 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.

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 holes are positioned 47mm apart.

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. The 2 holes are positioned 38mm apart.

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.

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

GARMIN® COMPATIBILITY

Our 4-Hole AMPS balls are compatible with certain Garmin® units. See our Garmin® Compatibility page to confirm fitment.

Get two if you have kids

Easy it install! I have two, both holding iPads in back for the long drives. Best part is when I’m not using the holder. It folds up.

2013 Ford Transit Connect

I installed this mount in my 2013 Ford Transit Connect. This year model is the same from 2010 to 2013. I drilled into the dash to the left of the stereo I installed. I used epoxy putty to fashion a base that conformed to the curve of the dash in this area. It's solid and is within easy reach of my right hand on the steering wheel. It is the perfect location. Very happy with my purchase.

Great mounting point

While there is no direct fit solution from Bulletpoint for a Subaru Crosstrek, and the mount I had from proclip placed my phone in the way of my radio, I found this mount ball uses the exact same mounting pattern as ProClip uses between their mount base and their mount. This allowed me to use their mount base in place of something like a rubigrid and then proceed with the bulletpoint system. This allowed me to get my phone mounted in a much better location.

Craftsmanship

Outstanding craftsmanship, sturdy only thing I didn’t care for is drilling into dash maybe a nutsert set to finish it off on detail aspects.

So far , excellent

It was very easy to install on my F-150 tremor. Y'all need a dedicated YouTube site that show simple installations however most of the ones I found on YouTube we're good I just wished it was one sponsored by the company that was complete and by the company itself it would have sped up things. But the equipment was excellent the installation was easy, just always want to be sure when you're installing it in a new vehicle that hasn't had modifications but everything worked out great I'm very happy with it even my wife who was giving me a hard time for buying more stuff for my truck finds it very cool. I teach school and even the kids find the equipment cool but at my age it's hard to be cool being 60 years old LOL

Flawless product as usual

I hate to overpay for anything, but sometimes the only way to get the best quality is to pay a little more. Bulletpoint products are not cheap, but they truly are the best. In my mind, worth every penny.

Easy to install. Solid.

Very easy to install and as a bonus, the RUBIGRID nuts that come with that, hold these in an even better position. I'd love to say I'd buy this again, but I'm pretty sure it'll outlast my truck.

Caution GM 14-19 for correct size

Great quality product and easy installation. But if you have a GM/Chevy 14-19 you will be using the smaller Ribigrid and the 4 hole mounts will not fit with all 4 screws. I was mounting a backup camera screen and wanted to have the broadest base to ensure stability. When I did the install, I realized the 4 hole mounts were too big and had to mount using only 2 screw holes.

Vast Number of Combinations

I purchased a package deal which included a base plate and a phone holder. I needed a second holder for my tablet so I purchased a few extra items. I have other reviews on this product but I will say again, you will not be disappointed. They product high quality, easy to install mounting systems. You can configure to your needs. Purchase with confidence!
