The AP032SM Dual-T-Tab to 4-Hole AMPS Adapter allows Dual-T-Slot holders to be mounted to a 4-Hole AMPS surface. The horizontal adapter measures 2.13 inches high x 1.63 inches wide-narrow enough to mount onto any flat surface, including car consoles or dashboards. Attach a Dual-T-Slot holder, including Arkon's Slim-Grip Ultra Universal Smartphone and Midsize Tablet Holder (SM060-2), Slim-Grip Universal Tablet Holder (TAB001), and Mega Grip Universal Smartphone Holder (SM040-2), or other Dual-T compatible component. The mounting pedestal is also compatible with older model (2005-2009) Magellan RoadMate, Triton, and Maestro GPS units that feature the Dual-T-Slot mounting pattern. The adapter can also be used with vehicle-specific mounts, including those offered by ProClip and Pro.Fit.
