iBOLTAMPS Adapter Plate

This has proven to be an excellent solution to mounting my phone in my car. I got the metal version, and I highly recommend it - particularly if you're using a strong magnet to hold your phone (like HaloLock, ESR - I suspect that a plastic mount would break being subjected to temperature changes and the force required to remove the phone.)I initially wished that the entire mount was the flat black color, but it ultimately doesn't matter that the ball is silver - it ends up being covered by the socket of the mount. The holes lined up perfectly and it installed in about 2 minutes. It does come with screws and nuts.

what I needed and worked great!

I attached this to a ProClip mount in a golf and it works like a charm. So far so good!

good solid mount

This little adapter plate does two things for you. Number one it makes it easy to install on most third-party vehicle mounting systems. But the biggest thing it does is prevent the 17 mm ball adapter from unscrewing during normal use. One problem with a lot of adapters is that they thread in so the right vibration or the right conditions will lead to your phone's weight at the end of it suddenly drooping or coming loose by unscrew the rear threads. This adapter doesn't have that problem. So all you have to do is secure the four holes on the outer portion of the plate and everything else is rock solid.If you have a very heavy device or mount at the end of this 17 mm ball, I highly recommend going with this mounting solution versus a threaded mount where the adapter itself simply threads under a single bolt. This design prevents casual loosening or unscrewing of the ball adapter while in use or during temperature change.Obviously if you have a mounting system that doesn't have a flat AMPS surface you may find this more difficult, but if you're using a system similar to proclip this will fit on most proclip exposed vehicle mounting surfaces. I recommend it for that reason. Also the tapping screws that come with most proclip adapters will properly secure these holes without tearing out.

I have a Garmin GPS and finally got tired of the suction cup always failing and taking the wire down with it. I built my own bracket out of sheet metal that attaches under the headlinder to the visor bolt assembly; and a secondary contact point on the windshield w/ a double sided 3m sticky for extra stability. This 4-bolt ball mount is a perfect fit (17mm) for the Garmin and works just fine. I got the plastic one and it seems very sturdy.Only 4 stars because the bag of machine screws/nuts only came with 3 screws and 4 nuts. Lol. Luckily I have a couple machine screws laying around so it wasn't a big deal

I was able to use this to attach my magsafe charger in my car to the in dash mount I bought which fit into the molding. It gives my charger the ability to swivel and feels very well made and secure.

I didn’t think the steal compare to the plastic was gonna make any difference. But it did. It hold it better and it feels more secure.
