This mounting plate secures a monitor or control handle inside the cab using a 1.5-inch ball-joint interface. The plate provides a rigid attachment point on a flat cab surface, allowing the operator to position the monitor within reach. The ball joint permits multi-axis adjustment of the mounted device. The assembly is designed to support a load within a specified range; exceeding that range can cause the joint to slip or the bracket to fatigue. When installing, ensure the mounting surface is clean and the fasteners are tightened to the manufacturer's specification.
