A RAM 1" diameter rubber ball is connected to the base allowing you to connect a RAM 1" diameter arm socket and connection plates to create the perfect mount for your application.

The clamp fit perfectly onto my car's window edge lip, and the 5/8-inch thickness capacity was spot on for my sedan. Setup took maybe two minutes, and now my tablet mount feels rock solid.

As a pilot, I finally have a solid mount for my iPad on the glare shield—the clamp fits perfectly on the lip edge. The ball base gives me plenty of adjustability, and it feels built to last through any turbulence.

I had a bit of trouble finding a mount that would hold tight to my car's window edge, but this clamp base fits perfectly on surfaces up to 5/8" thick without wobbling. It took less than a minute to install and feels solid as a rock.
