ذراع مقبس مزدوج RAM® - مقاس D متوسط

The spring-loaded tension knob lets me adjust the arm’s stiffness perfectly, and it hasn’t loosened at all after a month of daily use. This D-size medium fits my setup exactly, no wobble.

The ball socket clicks into place with a satisfyingly solid feel, and the tension is just tight enough to hold my tablet steady on bumpy roads. I was worried the D size medium wouldn't fit my setup, but it pairs perfectly with the standard ball bases I already have.

Installed this on my motorcycle mount and it holds my GPS steady even on rough roads. The ball-and-socket design gives plenty of adjustability without loosening up over time.
