A Keyboard Arm with Extended Above Desk Range
The Pinnacle AD is Workrite’s arm with the greatest range. It includes thoughtful features found in our Pinnacle family, like Lift-n-Lock™ for re-positioning and easy tilt adjustment with a built in tilt gauge. Ideal for situations where above desk keyboard platform is desired and stowing the platform under desk is convenient.

Extended Height Range & Storability
The Pinnacle AD features our greatest height range of 14½”, 7½” above work surface and 7” below. At 7” below, the Pinnacle AD meets the seated low requirement of BIFMA G-1 2002 for the 5th percentile adult female and exceeds the seated requirement for the 95th percentile adult male. In addition the Pinnacle AD’s extended above desk height range gives the majority of users the ability to work in standing positions. The unique design of the Pinnacle AD gives the best keyboard platform storage available in the industry, fully storing a platform as deep as 11½” under the work surface on a 22” track.

Tilt Range and Tilt Gauge
The Pinnacle AD features a full 25˚ range tilt based on the ANSI BIFMA G-1 2002 Ergonomics specifications of 10˚ positive tilt and 15˚ negative tilt. Our convenient tilt gauge at the rear of the arm allows users to identify the comfortable tilt angle and easily set the tilt to their preferred position with our dial-tilt knob located on the right side of the arm.

Stores Effortlessly on Ball bearing Track
The Pinnacle AD uses our high quality low profile progressive ball bearing track for ease of use and years of trouble free service. Available in 17”, 22” and 28” lengths the Pinnacle AD installs easily on all popular workstation depths. Also offered with a nylon track for budget conscious projects.
