This allows the grommet to be flushed against the desktop once installed, enabling easy access to 2x Power Outlets, a USB-A Charging Port, and a USB-C Charging Port right at the surface of your desk. Perfect for your office desk or other places where you need easy access to power. It comes with a 6.56ft power cord, long enough to accommodate most height adjustable desks while in motion. The built-in sliding cover is great for hiding the power grommet when not in use.
