Keyboard Tray Ergotron 77-050-200 Black Metal

The Ergotron Keyboard Tray 77-050-200 is a durable black metal keyboard tray designed to provide a stable surface for your keyboard and improve workstation ergonomics. It offers adjustable positioning options to help reduce strain on wrists and shoulders during extended typing sessions and fits a variety of desk setups when paired with compatible keyboard arms or pivots. This item is not a stand-alone product and must be ordered together with keyboard arms or pivots that are not included with the tray.

Advantages

The tray is constructed from sturdy steel and finished in black for a clean, professional appearance. The mouse platform can slide to either side depending on user preference, and the wrist rest holder is adjustable to better support different typing postures. Its solid build helps keep the keyboard stable while allowing ergonomic adjustments.

Suitable for

• Office desks requiring an under-desk keyboard solution
• Home workstations where improved typing ergonomics are needed
• Users who need a left- or right-positioned mouse platform

When it may not be suitable

This tray is not a complete mounting system and will not function alone; it requires compatible keyboard arms or pivots to attach to a desk. It may not be suitable for users who need an integrated tray with included mounting hardware or for desks that cannot accommodate an under-desk mounting arm.

Key specifications

• Material: steel (black finish)
• Mouse platform: sliding, can be positioned left or right
• Wrist support: adjustable holder
• Recommended load capacity: designed for standard keyboards (refer to compatibility with mounting arms)

How to use

Attach the keyboard tray to a compatible keyboard arm or pivot according to the arm manufacturer’s instructions, then mount the arm to the desk. Slide the mouse platform to the preferred side and adjust the wrist rest holder to a comfortable angle and height. Use the arm’s adjustment features to set the keyboard height and tilt for ergonomic typing posture.

What to consider before purchase

• Requires compatible keyboard arm or pivot—tray does not include mounting hardware
• Verify desk compatibility with the selected mounting arm
• Confirm the tray’s size and load capacity suit your keyboard and accessories

Usage recommendations

For best ergonomic benefit, combine the tray with an adjustable arm that allows you to position the keyboard at elbow height with a slight negative tilt; position the mouse platform so your forearm remains neutral while reaching.
