The Adjustable C-Clamp allows you to take your Mobitron Laptop mount out of vehicle and into the home or office to perform double duty. The unique two piece design fits together and offers four (4) different positions to accommodate various tabletop thicknesses. The large t-knob screw makes for easy tightening and securing the clamp to the tabletop. The C-Clamp is designed to work with the Universal Vehicle Laptop Mount for mounting computer LCD monitors in a office environment. Attaching an LCD monitor is as easy as unscrewing four thumb screws and removing the VESA mounting bracket from the deck. Simply attach the bracket to the computer monitor then attach the post the C-Clamp. You now have an instant monitor stand for your desk or display.
