This mounting pedestal is extremely versatile and can be used as a replacement, upgrade, or as an addition to an existing pedestal with a 4-Hole AMPS pattern. It is compatible with devices having a 4-Hole AMPS pattern, including cameras, GPS devices, audio/video receivers, or satellite radios including Sirius S50, Sirius XM Onyx Plus, XM Onyx EZ, Sirius XM Lynx, Stratus 7, Dock & Play, and Sirius Dock & Play (sold separately). This mounting pedestal is also ideal for mounting mobile radio holders, housings, and other devices used by public safety, construction, and utility applications. This sturdy mounting pedestal measures approximately 6 inches from end to end and features three adjustment knobs at approximately 1.25” intervals on the mount arm for easy positioning. The 4-hole drill base mount is made of strong aluminum, and is ideal for environments where a more permanent solution is desirable, such as in a workshop or in retail. Screws and anchors are included. Formerly an industry standard, the 4-Hole AMPS pattern consists of four holes located in a rectangular pattern spaced at 30.17mm by 38.05mm (measured as the center-to-center distance between holes).
