RAM® 3 英吋方形柱夾具支架（附圓形 AMPS 板）- 中型臂

The clamp grips my 3-inch post firmly with no slippage, and the medium arm provides just the right amount of adjustable reach for my GPS. That AMPS plate lined up perfectly with my existing mount holes.

Three-inch post was a perfect fit with the clamp, and the AMPS plate lined up flawlessly with my device holder. The double socket arm holds its position even on bumpy roads, which is exactly what I needed for my field work.

The clamp grips my square post solidly, no wobble even on bumpy roads, and the 6-inch arm gives me just enough reach to angle my tablet perfectly. The AMPS pattern on the round base lined up with my device's plate without any drilling.
