RAM® 楔形球頭轉接器 for RAM®、Attwood 及 Fish-on 底座 - B 尺寸

The wedge design makes it incredibly easy to create a secure mount in my rod holder without any tools. I love how it stays firmly in place even when bouncing around on rough water.

Took about ten seconds to slide this wedge into the rod holder opening, and the fit is snug enough that there's zero wobble once the ball's seated. The simplicity of the design is exactly what I wanted for adding a mount without drilling into anything.

Finally, a clean way to mount a ball on a rod holder without any extra hardware. The wedge design slid right into my existing base and locked solid—took maybe ten seconds.
