    Quick & Easy

    The RAM 1/4" -20 Female Threaded Hex Hole with 1" Ball, enabled me to use my camera tripod with the RAM Tab Tite Cradle. This makes video conferencing on the tablet super easy no matter where I am. It takes seconds to install and just works. (The addition of a large stainless flat washer with a 1/4" hole helps the Ball mount screw tight without sinking into the cork base on my tripod)

    Awesome idea!

    This allows you to use any camera tripod with Ram Ball products. Very useful for action cameras to be mounted everywhere with Ram Ball, and able to tilt in any direction.
