The RAM-B-149Z-AP8LU consists of a zinc coated u-bolt base, double socket arm, locking knob and Latch-N-Lock model specific cradle for the Apple iPad 4, iPad 3, iPad, iPad 2 and iPad 1. The mount is designed with a RAM 1″ diameter patented rubber ball and socket system that has adjustment points at both ends of the double socket arm; this allowing for almost infinite adjustment and perfect viewing angles. Included in this package is hardware that will accommodate rails from 0.50″ to 1.25″ in diameter. The base includes black cover caps to be placed over the exposed ends of the u-bolt. The included composite rail adapter can narrow the rail to a minimum width of 0.5″. The cradle includes a dial combination lock for security against theft, along with 4 mounting points with pre-drilled holes on the back. The locking knob attaches to the double socket arm, combining with the dial combination lock, creating the ultimate anti-theft mount for your iPad.
