The AP016-3M Dual-T-Slot to 4-Hole AMPS Adapter allows Dual-T-Tab pedestals and mounts to be mounted directly to flat surfaces, such as car dashboards or consoles. This vertical adapter measures 2.38" tall x 1.63" wide, and can be mounted with either the included 3M adhesive or screws (not included) onto any flat surface or onto a satellite radio or other device with a 4-Hole AMPS mounting pattern. Dual-T-Tab pedestals or mounts can then be attached to the adapter. This adapter provides a quick-release function for those wanting to attach and remove their devices frequently. The adapter can also be used with vehicle-specific mounts, including those offered by ProClip and Pro.Fit.
