RAM® 45度 1/2インチ NPTネジ穴付きラウンドベース

The 2.5" round base is solid and the 1/2" NPT threads engaged smoothly on my rigid arm setup. It holds my device at a perfect working angle without any sag.

The 45-degree angle on this base is exactly what I needed to route my rigid arm assembly around a tight corner, and threading it onto the 1/2" NPT male connector was smooth with no cross-threading. The 2.5" round base feels solid and machined well, so I’m confident it’ll hold up under constant vibra

The 2.5" base fits perfectly on flat surfaces, and the 45-degree angle is just right for my setup. Threaded onto a rigid arm, it holds firm without any wobble.
