iBOLT™ Industry Standard 17mm Amps Plate

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

what I needed and worked great!

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.

This company was very helpful and responsive to my needs. Excellent transaction, I would purchase from them again.

This is a good ball mount for a cell phone holder. I used it to install a phone holder in my ATV. Hold the phone very secure. Came with machine screws. I used some black sheet metal screws to mount this to the dash on the ATV
