Christopher Y. ★★★★★ Oct 23, 2026

The rubber ball joint on this base makes it easy to adjust my GPS mount to just the right angle on a 1.5-inch rail. Clamps down securely without any slippage, even when I hit a bumpy stretch of water.

Andrew ★★★★★ Oct 22, 2026

Installed this on my boat's railing and the rubber ball held firm even in rough water. Fits my 1.5-inch pipe perfectly with no slipping.

Penelope ★★★★★ Oct 20, 2026

The rubber ball on this base grips my boat's railing tightly without scratching the paint, and the clamp adjusts easily to fit the 1.5-inch pipe I have. It's rock solid even when I mount a heavy GPS unit on it. Exactly what I needed for a secure install.
