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.

Confirm smooth ball-bearing travel on the 9.2 inch wide track and test the 10° positive to 15° negative tilt range.
