RAM® ドリルダウンマウント シングルソケットアーム＆大型ラウンドプレート

The round plate is exactly the right size for my setup and the socket arm locks down with no wobble at all. I’ve been using it for a few weeks on the boat and it handles the vibration from the motor without loosening up.

I needed a sturdy mount for my downrigger, and the 3.68" round base fit perfectly on my boat's flat surface. The whole kit feels rock-solid, no wobble even with the socket arm fully extended.

The socket arm clicks into place with reassuring precision, and the whole setup holds my downrigger steady even in choppy water. Installation was straightforward with the included hardware, and I feel confident it won't loosen over time. Exactly what I needed for a secure, adjustable mount on my boa
