The RAM® Single Pivot Mount with Knob (RAP-101-PV4U) is a low-profile, drill-down mounting solution. Each end features 2-hole and 4-hole AMPS patterns to easily install any RAM® holder or GDS® dock and secure the mount to any surface. This solution uses tooth-lock washers to allow users to pivot their device up to 180-degrees, and the extended knob makes it easy to adjust the viewing angle of your device.
