The Value Adjustable Height Mechanism is a nylon-track mechanism that mounts to the underside of your worksurface, allowing your keyboard tray to slide in/out and adjust up/down for ergonomic comfort. The track determines how far back the tray can be tucked when not in use — longer tracks tuck deeper.
Specifications
- Nylon track — smooth, quiet, low-maintenance
- Adjusts from flush to 6″ below worksurface
- Tilt range: -15° to +10°
- 360° swivel
- Low-profile design — 5.75″ wide
Choosing a Track Size
Measure the flat usable space on the underside of your desk (front to back). The longer the track, the further the tray tucks under your desk when not in use.
- 17″ — fits most desks 24″ deep or shallower
- 21″ — recommended for desks 30″ deep, allows full retraction
Note: All keyboard trays must be used in conjunction with an adjustable arm mechanism. This mechanism does not include the tray.
