Arkon 4 inch 4-Hole AMPS Drilled Base Mount - 4-Prong Compatible

Standing 4.25 inches from end to end, this compact pedestal suits confined spaces where a shorter mount works best. It accepts 4-Prong pattern device holders, cradles, adapters and other components, each sold separately. The shaft is built from composite for a tough, low-vibration platform, and the double-socket arm pivots at both the upper and lower joints for full 360-degree rotation, so you can settle your device at virtually any angle. The 4-Hole AMPS layout is four holes in a rectangular arrangement measuring 30.17mm x 38.05mm centre to centre between holes. You can also fasten the base straight into your vehicle floor. (Warning: drilling into a vehicle floor may cause damage. Take care and speak with a professional mobile installer so you avoid drilling through any sensitive vehicle components.)
