WR-S2S Sit-Stand Keyboard Tray Solution offers exceptional height adjustability

The WR-S2S lifting mechanism and keyboard tray is a unique system that transforms your keyboard into a high performance sit-stand device. It is a significant design improvement over the decades old and vertically restricted articulating arm design. Linear up and down travel is achieved by a scissor lift mechanism that outperforms traditional variants in terms of height adjustment and space efficiency. Combined with an Ergomart monitor arm, users of all heights can quickly move from sitting to standing in seconds. The WR-S2S is designed for use with both normal depth and limited depth straight work surfaces. Some corner desks are also compatible, but require a 22" or wider diagonal corner for the compact keyboard tray and a 24" or wider diagonal corner with the standard keyboard platform.

The WR-S2S features:

  • 22.75" vertical adjustment (16.25" above and 6.5" below the work surface)
  • 30° keyboard tray tilt range (-20° to +10°)
  • Under surface travel along the under-desk nylon glide track (17" or 22")
  • Design geometry delivers linear vertical travel throughout its range
  • Two platform tray options:

Compact Keyboard Platform

Standard Keyboard Tray option

  • Designed for compact keyboards under 6" deep
  • Included removable palm support
  • Left- and right-handed compatible
  • Constructed with durable .25" solid phenolic
  • Fully stows under desk on 22" track
  • Sits 3" past front of 17" track when stowed
  • Available in black

Standard Keyboard Platform

Compact Keyboard Tray option

  • Includes document holder & cable management
  • Comes with removable palm support
  • Constructed with durable .25" solid phenolic
  • Sits .75" past front of 22" track when stowed
  • Sits 5.75" past front of 17" track when stowed
  • Available in black

Vertical adjustment requires no knobs or levers - simply tilt the keyboard tray up, position the tray at the desired height and then release and it locks into place. Rotate the tilt knob to dial in the most comfortable tilt angle. Once lowered below the desk work surface, the keyboard tray and arm can be retracted beneath the desk along the track.

The entire system is built with high-quality materials that are guaranteed to last. The keyboard arm meets ANSI/BIMFA X5.5 standards and the tray is constructed from durable .25" solid phenolic.
