Cradle, Universal, Small Size
Plastic cradle for most any cell phone or similarly sized device. The button on the left/bottom of the cradle releases the spring loaded sides so they can extend to their maximum width.  As you squeeze the sides in they click and hold to clamp onto your device.  The sides are padded with a soft foam rubber which holds on to the device.  Mounting screws are nuts are included which can be used to mount the cradle to any RAM diamond shaped mounting base such as a RAM-B-238 or RAM-A-238.  It seems to work well with phones but the soft sides wouldn't hold a PDA very well.  It is not wide enough to hold iPAQ PDAs.  It seems to hold a Colibri GPS flight recorder quite nicely (see photos at right).  Can accommodate items from 40 mm (1.57 in) to 70 mm (2.76 in) wide.
