RAM® 方形立柱夾具支架 適用於寬度達 4 英吋的立柱

Clamped this onto a 3-inch post on my ATV and it holds my phone rock-solid even over bumpy terrain. The AMPS pattern on the 2.5" round base lined up perfectly with my existing cradle. Exactly what I needed for off-road use.

The double socket arm keeps my GPS perfectly positioned even on rough trails, and the clamp fits my 3-inch trailer post without any wobble. Exactly what I needed for a secure truck mount.

The double socket arm gives me just enough adjustment to angle my device perfectly, and the clamp grips my 3.5-inch post without any wobble. Took a couple minutes to tighten everything down, but once it’s set it stays put.
