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

I use them to make custom magsafe mounts.

Very sturdy

This is a very good quality product. Works well. Much better than the plastic one.

Loved this mount for 2 years!! Then the weather got really hot here in the southeast US. Now, I cant crank the mount tight enough to grip this ball mount on a hot day. I think the hot aluminum ball on the mount is actually melting the plastic surface of my car mount & keeping it too loose to use.

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

VERY WELL MADE, VERY REASONABLE PRICE... I WAS ABLE TO RECONFIGURE THE BALL PART TO FIT A CUSTOM MOUNT IN MY 2018 JEEP WRANGLER TO HOLD MY CELL PHONE AT DASH LEVEL SO THE MY LINE OF SIGHT WAS STILL OBSEREING THE ROAD WHEN GLANCEING AT THE PHONE...

Very good quality. Much better than cheap plastic stuff. This is top quality and will last without breaking!

Exactly what we were looking for for our MagSafe phone mount. Well made & fast shipping.

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

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