PinnacleArm 22 inch Ball Bearing Track

The Workrite Ergonomics 3170-22TG PinnacleArm is a chair and furniture accessory designed to mount a keyboard platform beneath a worksurface. Its slim mounting bracket preserves full knee clearance while the 22 inch ball bearing track enables smooth, stable extension and retraction. The unit is sold new and meets ANSI/BIFMA X 5.5 1998 standards for performance and durability.

Suits users needing one-touch height control

The Lift n Lock mechanism adjusts height from flush to 6 inches below the worksurface without knobs or levers, while the platform tilts from 10 degrees positive to 15 degrees negative. A 360 degree slide-track swivel aids positioning and storage. Buyers who require a longer track length of 21.8 or 27.8 inches, or who prefer a nylon guide Value Arm, should consider other configurations.

Sustained daily adjustment without wear

Ball bearing guides maintain consistent glide over repeated cycles, and the construction satisfies the ANSI/BIFMA X 5.5 1998 cycle testing requirements. The one-touch height lock engages positively each time, and the tilt range stays fixed through continuous repositioning. The limited lifetime warranty covers the product for the duration of ownership.
