كرة RAM® Tough-Ball™ مع مسمار تثبيت 1/4-20 بوصة

The 1" rubber ball has held my phone mount perfectly steady on rough gravel roads without any sagging. Installation was simple since the 1/4"-20 lag bolt threaded directly into a pre-drilled hole in my dash.

The 1/4"-20 threaded post screwed into my dash mount perfectly, and that 1" rubber ball holds tight even on rough gravel roads. I've had it on for three weeks and it hasn't budged a millimeter.

The rubber ball has a nice grip that holds my device firmly in place, even on bumpy trails. I was pleasantly surprised at how easy the 1/4"-20 lag bolt was to install into my existing setup.
