Arkon's PPTAB106 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 multi-angle mount with 9 inch arm. This sturdy mount features three adjustment knobs at 2.5'' intervals on the mount arm for easy positioning. Two additional 180° adjustment points at the top and bottom of the mount provide additional flexibility in positioning the device. 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. This mount can also be drilled directly into the floor of a car or truck. (Warning: Drilling into the vehicle's floor may damage the vehicle. Use caution and consult a mobile install professional to avoid drilling into any sensitive vehicle components.) Adjust the 9'' multi-angle 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.
