The SR575M SmartMountTM Full Featured Flat Panel Cart takes our standard cart to the next level, making everyday usage more enjoyable. Height adjustment of the display and component shelf can be made without the removal of the display by simply repositioning to your desired height and the fear of damaging doorways and walls has been averted by non-marring bumpers on each corner of the cart allowing even easier mobility from room to room while the UL certification ensures you that it can be done with safety in mind.
