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:
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.
The keyboard tray mechanism lifts 16.25" above the top of the track and 6.5" below, giving a total vertical travel of 22.75". The track is available in either 17" or 22" lengths. In the lowest position, the distance from the edge of the worksurface to the front of the keyboard tray mechanism is 12.25".
The keyboard tray platform has 20° negative and 10° positive tilt.
The track is 5.75" in width. The scissor arms have a maximum width of 21" when placed in the "sitting" position and a minimum width of 9.75" when placed in a "standing" position.
The compact keyboard tray measures 25" x 9". The removable keyboard palm rest is 17" x 2.1", making this platform ideal for smaller keyboards less than 6" in depth.
The standard keyboard tray measures 27" x 11.5". The removable keyboard and mouse palm rest is 26.25" x 2.6". The rear of the platform includes a document holder and cable management.
