This No-Drill™ Laptop Stand System installs quickly and easily into the specified vehicles using the existing hardware of the passenger side seat rails. This configuration provides a telescoping feature with upper and lower poles that allow you to set your mount to the desired height with the simple turn of a knob. Dual swing arms provide articulation and 12 inches of reach for passenger and driver access to the mounted device. Patented rubber ball and socket joint provides additional adjustment as well as shock and vibration isolation. The RAM Tough-Tray™ is spring loaded to accommodate 10" to 16" wide laptops (17" wide screens). The tray features four adjustable retaining arms with rubber grip feature. These arms can be moved both vertically and horizontally. This allows for a custom fit for varying thicknesses of laptops and the freedom of not blocking ports or drives. A screen support and USB light are also available to accessorize the tray. Hole patterns on perimeter of tray facilitate the mounting of additional RAM systems to support GPS or other electronics. The included Pin-Lock™ security locking system is designed to prevent tampering and theft of your laptop. With an emphasis on aesthetics and function, the security knobs are low profile and only add a small amount of additional bulk to your system when compared to the standard knob included. At a fraction of the cost of currently available keyed locking knobs, the additional peace of mind and tamper resistance comes at a very affordable price.
