The SM6HD005 heavy-duty drill base mount with 10 inch adjustable arm fits midsize (7'' or 8'' screen size) tablets, including iPad mini, Galaxy Tab S 8.4, Galaxy Note 8.0, Galaxy Tab 4 or 3 7.0 and 8.0, Galaxy Tab Pro 8.4, and Google Nexus 7. It also holds smartphones up to 6.75'' tall (8'' screen size), including iPhone XS Max, iPhone XS, iPhone XR, iPhone X, iPhone 8 and 8 Plus, iPhone 7 and 7 Plus, Samsung Galaxy S10, S9, S8, S7 edge, and S7, Galaxy Note 9, Note 8, and Note 5, LG G6, G5, and G4, Nexus 6 and Nexus 5, Nokia Lumia 1520 and 1020, Motorola Moto G and Moto X. This mount includes Arkon's Slim-Grip Ultra Universal Holder and Heavy-Duty Aluminum Mount with 10'' Adjustable Arm and 4-Hole Drill Base. The 4-hole drill base mount is made of strong aluminum, and is ideal for flat surfaces where a more permanent solution is desirable, such as a workshop table or retail counter. Screws are included. Bend the 10'' adjustable arm and rotate the swivel ball adapter head for 360° rotation for exact positioning of the tablet or smartphone. The top and bottom adjustable-leg design of the Slim-Grip Ultra Holder helps keep any side buttons and ports unobstructed, making it ideal for use with the side accessible buttons on the Samsung Galaxy S6 edge or Note Edge. The patented spring-loaded holder expands to accommodate all devices, even those with skins and ruggedized cases. Included with the holder are 8 support legs (4 short and 4 longer versions) that can be customized based on device size. For most devices, the best mount holder configuration is to attach 2 short support legs on top and the 2 long support legs on the bottom of the holder. For larger devices, use all 4 long support legs on the holder. For smaller devices, use all 4 short support legs on the holder.
