RAM® 方柱夾具底座 適用寬度達1.7吋的立柱 - D尺寸

The clamp fits my square post perfectly and the rubber padding keeps it from scratching the surface. Locking it down took less than a minute and it feels solid enough to trust with my tablet mount.

The 2.25" ball locks in tight with zero wobble, and the clamp handles my 1.5" square post like it was made for it. Solid piece of hardware that feels like it'll outlast the truck.

I needed a solid mount for my GPS on my boat's square railing, and this clamp base held firm even through some choppy water. The adjustable width really helped get a perfect fit on my 1.5-inch post.
