RAM® 方形立柱夾具底座 (適用於寬度達2.5吋的立柱) - E尺寸

The clamp grips my 2-inch post firmly without any wobble, and the rubber coating is a nice touch to protect the paint. Setup took me maybe 10 minutes with a hex key, and now my tablet mount feels rock solid.

I needed something sturdy for my deck railing, and this clamp base locks onto the 2.5" square post without any wobble. The E size ball system feels solid enough to hold my heavy tablet mount securely.

The clamp feels incredibly secure on my 2-inch square post, and I love that the ball gives me full adjustability. It’s a relief to finally have a mount that doesn’t wobble, even with a 10-pound tablet attached.
