RAM rail mount with universal Tough-Tray™ II netbook/tablet holder. The zinc coated rail mount accommodates piping from 0.50" to 1.25" in diameter. The RAM Tough-Tray™ II is spring loaded expandable tray that can accommodate netbooks and tablets that are 8.56" to 12.31" wide. Spring loaded to create just the right amount of holding force, most tablets, UMPC’s, and compact laptops can be made safe and secure while on the go. Simple to install and adjust retaining arms insure a perfect fit without interfering with ports or functions. Also, if a compact laptop is in place, these retaining arms hold firm with the screen up or down.
