RAM® ボールアダプター Fusion StereoActive用 - Cサイズ

I've got this attached to my pontoon's railing and it holds my speaker rock-solid even when we hit a wake. The C-size clamp fits the speaker perfectly with zero wobble.

Took about five minutes to snap onto the RAM ball mount, and now my Fusion speaker stays put even when the boat hits a wake. The rubberized grip on the C-size adapter feels solid and doesn't wiggle at all.

Finally, my speaker is securely mounted to the boat rail without any wobble, even when we hit some decent chop. Took under a minute to snap the C-size adapter onto the ball and lock it in place. Exactly what I needed for a waterproof Bluetooth speaker that stays put.
