With the window up while shooting sound or down for some fresh air, or up and down during the take, the Brauer Mount is the only Hostess Tray that will do both. The Brauer Hostess Mount will allow you to accomplish all that and mount nearly any camera package or even a gimbal stabilization system safely and securely in less than 5 minutes. The 10"x14" aluminum cheese plate slips between the window and door of nearly any vehicle and securely ties to the side of the car with vacuum cups, 5/8" Rods, grip heads and quick struts. In addition, the door can be opened and closed without restrictions, a real convenience for your talent. If you have any mechanical aptitude at all, you can use the ingenious design of the Brauer Mount to jimmy the door and jack the car (but you didnt' hear that from us).
