This universal round mounting plate provides a 1.5-inch ball-joint interface for attaching a monitor or terminal inside the cab. It is designed to support loads from 1 to 4 kg, making it suitable for holding displays used in baler applications. The plate serves as the fixed base between the cab structure and the monitor arm or handle, allowing the operator to position the screen for visibility. A worn or loose ball joint causes the monitor to drift or vibrate during operation, reducing readability. The manufacturer machines the ball to match the socket dimensions of the original handle assembly, ensuring consistent clamp force without the need for shims.
