If you've put a RAM ball on the back of your Perfect Squeeze phone mount, then you'll need a RAM arm to go with it. Allows easy adjustment to get your phone positioned just right. Arm is 3.69" long and works with any 1" RAM ball.
This mount is great. Very easy no drill install that only takes minutes. Very sturdy as well as adjustable for each person's preference. Highly recommended.
Just returned from a 3k mile trip without any problems and this Ram arm worked as it should. I had a Ram arm for a trip last year that failed at 2.5k miles, threw it in the trash. Hopefully this arm will hold up for a few years.
