Customer Reviews (4.4 / 5 · 5 reviews)

Sofia ★★★★★

I needed a secure mount for a 4-inch railing, and the 1.5" rubber ball grips firmly without slipping. The clamp base feels solid, though you’ll need to grab your own bolts since hardware isn’t included.

Sebastian ★★★★★

Installed this on a 3.5" square rail and the rubber ball clamps down securely with no slipping. The fact that it fits up to 4" width without needing extra hardware saved me a trip to the hardware store.

Sophia B. ★★★★☆

I needed a sturdy base for my boat rail, and this clamp fits perfectly on posts up to 4 inches wide without any hardware hassle. The 1.5-inch rubber ball grips tight and holds my device steady even on bumpy rides.
