Ultra-Compact Arm, 28" Ultra-Compact Keyboard and Mouse Tray
Ultra-compact keyboard and mouse tray for ergonomic support on height-adjustable desks and furniture, featuring a 5.75" height adjustment range
The Chief KBD-UC-UC is an ultra-compact keyboard and mouse tray designed for high-performance ergonomics in spaces with limited clearance. It is optimized for applications requiring maximum retraction under a desktop and minimal track length, making it an ideal solution for height-adjustable desks with cross-members positioned as little as 12" (305 mm) from the front edge of the work surface. This assembly features a patented secondary slide and a unique arm design to maintain a compact footprint while providing full retraction via an 11" (279 mm) track. The system utilizes a patented "No Knob / Gravity Lock" spring-assisted height adjustment, allowing users to simply lift the tray to the desired position and release it without the need for knobs, levers, or ratchet handles. The phenolic surface tray is paired with a rugged steel arm finished in a durable black powder coat, meeting or exceeding ANSI / BIFMA X5.5 industry standards for durability.
