The double socket design makes adjusting my GPS mount effortless, and that jam nut keeps everything rock solid even on rough trails. Exactly what I needed for a clean, secure setup.

Robert ★★★★★ Oct 22, 2026

Finally got this mounted on my truck's dash and the jam nut design locks it solid—no wobble even on rough roads. The dual socket arms make adjusting my GPS and phone holder quick without fiddling with tools. Exactly the sturdy, versatile arm I needed for my setup.

The spring-loaded sockets grip those 2.25" balls with a satisfying click, and the jam nut locks everything down tight without any wobble once it's snug. I've been swapping my device between two mounts daily for a week and the arm hasn't loosened a bit.
