ARKON Metal 4 Hole AMPS to 17mm Ball Adapter Retail Black (APAMPS17MET)

This ball creates a sturdy support for any 17mm socket. Best I have ever purchased.

works perfect for my Garmin dezl

just what i needed for my phone holder in a big truck

Very sturdy

This is rock solid 17mm mounting ball thats compatible with many accessories. I use this in conjunction with my magsafe car charger. I have one in each of my 3 vehicles.

This IS magnetic, if you were wondering - this will very strongly stick to any of the popular magnetic neodymium GPS/phone mounts.

For my GPS to be mounted to the center of my batwing fairing.

I use them to make custom magsafe mounts.

I needed an AMPS mounting plate and 17mm ball head to fit my phone mount to a custom car mount. This was perfect and is well made. For a specialty product, the price was really good too.

This is great. I had a plastic one before this and it eventually broke. This one is all metal and has held up very well.
