RAM® ボールアダプター（Fusion StereoActive用） - Bサイズ

Took this adapter out on the pontoon last weekend and it held the speaker perfectly even over some choppy wakes. The B-size ball mount clicks into place securely and doesn't budge.

Finally stopped worrying about my speaker sliding around on the deck—this B-size adapter is a rock-solid fit and locks in with that satisfying click. Took the speaker out on a choppy lake day and it never budged, even with the waves bouncing the boat.

Snapped right onto my existing RAM mount setup on the camper, and the B‑size adapter holds the speaker secure even on bumpy roads. Took maybe 20 seconds to lock in place.
