Edward G. ★★★★★ Oct 23, 2026

The rubber ball on this mount grips perfectly, no slipping at all since I installed it on my truck seat. That threaded stud is exactly the right size for my accessory, and the whole thing feels rock solid on rough roads.

I needed a solid mounting point for my GPS and this rubber ball holds it tight without any wobble even on rough roads. The 1" diameter ball gave me just the right amount of adjustability for perfect screen positioning.

The 1" rubber ball feels really solid, and the 3/8"-24 threaded stud threaded in perfectly without any wobble. Used it to mount a phone cradle on my motorcycle and it hasn't budged on rough roads.
