Compatible Keyboard Tray for 100 Series

This Ergotron keyboard tray is designed specifically for the 100 Series pivot and arm systems. It is not a stand-alone unit and must be ordered with compatible mounting hardware. The accessory targets office workers who need an integrated input surface on an existing Ergotron 100 Series installation.

Adjustable Mouse Tray and Wrist Rest

The mouse platform slides to the left or right side to match hand dominance. An adjustable wrist rest holder supports varied typing postures. Capacity is limited to a single keyboard and mouse combination; it does not accommodate additional peripherals or oversized input devices.

Sturdy Steel Construction in Grey

The tray uses a steel frame finished in grey for durability in daily office use. Mounting depends entirely on the 100 Series pivot or arm ordered separately, so desk attachment points are dictated by that hardware. No standalone feet or clamps are included with this tray.

Questions about this item

Will the 77-050-200 tray attach to my existing 100 series pivot arm?

Yes, the tray is designed for the 100 series pivot and must be ordered with compatible keyboard arms or pivots that are not already bundled with a tray.

How can I confirm the mouse tray slides correctly after installation?

Test the mouse tray by sliding it to both the left and right positions; it should move smoothly in either direction depending on your preference.

Does the 77-050-200 package include a keyboard arm or pivot mechanism?

No, this is not a stand-alone product; the tray arrives without a keyboard arm or pivot, which must be purchased separately if you do not already have a compatible 100 series unit.
