Arkon's PPTAB105 portable mobile printer drill base mount is ideal for holding portable mobile printers, including those from Zebra, Epson, and Brother in your car or truck. This mount includes Arkon's Slim-Grip universal holder and mount with 10 inch adjustable arm. The 4-hole drill base mount is made of strong aluminum, and is ideal for environments where a more permanent solution is desirable. Screws are included. Bend the 10'' adjustable arm and rotate the swivel ball adapter head for 360° rotation for exact positioning of the device. The mount's holder features a spring-loaded design that makes it easy to insert or remove the printer by pushing down on the lower legs of the holder with one hand. Included with the holder are 4 support legs (2 short and 2 long versions) made especially for holding mobile printers. Choose the 4 legs that provide the best fit for your portable mobile printer. These insert at the top and bottom of the holder and can be easily adjusted in order to keep any side buttons and ports unobstructed. The holder can also fit large tablets with 7''-18.4'' screen size by switching out the printer support legs for the tablet support legs that are also included. Note: some mobile printers may need a combination of printer and tablet legs for best fit.
