Timothy ★★★★★ Oct 23, 2026

Installed this on my boat's dash and the single socket arm holds my GPS firmly even when hitting wakes. The 1.5" ball mount clicks in solid with zero wobble.

Ava ★★★★★ Oct 22, 2026

The threaded 1/2" NPT hole mates perfectly with my existing mount, and the socket grips the C-size ball snugly with zero wobble. It swings smoothly and locks solidly, exactly what I needed for my setup.

Natalie ★★★★★ Oct 21, 2026

I needed exactly a 1/2" NPT threaded mount for a custom antenna base, and this socket arm locked onto the ball mount with zero wobble. It's surprisingly compact for how much adjustability it gives you.
