Ergotron Mounting Adapter for Mounting Arm - Anodized Silver

This fixed rotation kit with two stop posts controls the range of motion of the LX arm, so the extension doesn't come in contact with a desk panel or divider on either side of the post.

• Provides a fixed 180-degree stop
• Prevents the extension arms from hitting the wall
• Easily attaches to the pole and secured in place with two set screws to prevent stop rotation
