RAM® 11mm 볼트 헤드 어댑터 포함 더블 볼 마운트

I was a little worried the 11mm bolt hole wouldn’t match my bike’s setup, but it fit perfectly with the included diamond base adapter. The whole thing feels rock-solid on rough roads, and the ball mount adjusts easily without any tools. Exactly what I needed for a secure phone holder.

The double socket arm has zero wobble once you tighten it down, which is exactly what I needed for my bike’s handlebar. The 11mm hole fit my existing bolt without any extra shims, though the diamond base is a bit bulkier than I’d like under the mount. Still, solid and secure for the price.

The 11mm bolt hole lined up perfectly with my existing hardware, so installation took under five minutes. The double socket arm holds my phone steady even on gravel roads, though I wish the diamond base adapter came with a wrench for tightening.
