The Proaim Top Shelf is ideal for increasing workspace and keeping your computer, keyboard, or stands on your Camera production cart. The tray is constructed with high-grade CNC Aluminum for life-long durability. The shelf is edged from 3 sides to prevent items from falling off & one side is kept without an edge to provide accessibility for the keyboard. The Proaim top shelf does not need any tools for mounting; it rests on the four cart poles, all you have to do is lock the knobs, and it’s done. The two handles on the sides offer the ease of mounting/dismounting. A pass-through cable hole allows you to manage your cables easily. In addition, the Proaim top shelf is provided with a mat that prevents items from sliding off.
