RAM® ボールアダプター メス型 RAM ROD® ラチェット付き

The ratcheting mechanism locks tight and the groove system fits perfectly into my existing rod mount. Swapping between accessories has become effortless, and the build feels solid.

The groove ball adapter locked into my existing rod mount perfectly on the first try, no wobble at all. Exactly what I needed to add a ball mount without buying a whole new setup.

The little ratchet mechanism clicks into place with a satisfying precision, and it locks onto my rod holder tight enough that I don't worry about it shifting on rough water. Took me about a minute to swap between setups, which is exactly what I needed.
