Introducing the Mid Level Tray for Boulder Camera Cart This Tray can be easily mounted to the main support posts of the camera cart in order to provide an additional surface at varying heights. It uses Tool-Free locking screws to mount to the support bar that connects the carts legs on each side. Users can then adjust the height by raising or lowering the support brackets to accommodate different sized cases or accessories. This is especially useful when mounted higher as it creates a thin extra shelf for storing tools and other smaller parts, while still leaving a large space on the bottom for storing cases and other larger items.
