RAM® 大型マリンエレクトロニクス用スチール補強ボールアダプター - Eサイズ

The steel reinforcement gives me confidence it won't crack under heavy marine use, which was my main worry with plastic adapters. I had to drill one extra hole for my specific device, but the bracket itself feels rock-solid.

Dropped my old mount twice before switching to this adapter. The steel reinforcement gives real confidence that my expensive plotter won't end up on the deck. Fits perfectly in the pre-drilled E-size ball base I already had.

The multiple pre-drilled hole locations saved me a ton of time fitting it to my existing electronics, and the steel reinforcement gives it a solid, reassuring weight. Fastened everything down tight and it hasn’t budged in rough seas.
