Tenor Trackless Keyboard Arm

The Tenor Trackless Keyboard Arm from KV Waterloo was designed to require the minimal amount of undersurface mounting space while still providing storage for keyboard trays up to 9.5" in depth. Requiring just 9.375" of mounting depth, the Tenor Trackless Keyboard Arm features a direct mount which is ideal for situations where there simply is insufficient space to accommodate a traditional track-mount keyboard arm. It will permit full storage of trays up to approximately 9" deep. While 11" deep trays can also be mounted only about the first 9" of depth will be stored (i.e. on an 11" deep about 2" of tray will protrude).

The Tenor Keyboard Arm has all the features of traditional "tracked" arms. Keyboard height and storage are easily accomplished employing a simple "Lift-N-Lock" mechanism and angle adjustment (+10° to -15°) is a simple Dial-A-Tilt. Clearly readable independent gauges behind the tray show the current elevation and angle. Elevation ranges from -1.25" to - 7" below the mounting surface, a full 5.75" of range. The Low Profile head ensures optimal knee and leg clearance at all positions—even when fully stored the arm extends only 5.75" below the mounting point. The arm also features a full 360° swivel mount, offering the potential for full storage of deeper trays by rotating the tray below the desk surface when sufficient clearance exists.

Sit-Stand desk users who desire a keyboard arm may find that the direct mount and compact design of the Tenor Trackless Keyboard Arm result in less vibration transfer to their monitors than do traditional tracked arms. As well, the trackless "direct mount" design lends itself to installation on desks with crossbars which would normally render the installation of a tracked keyboard arm impossible. However, if there is sufficient space to accept a 15.25" deep track the Staccato Keyboard Arm may be a better alternative. It will accommodate similar tray depths with the same restrictions - ie. 9" deep trays will store, 11" deep trays will protrude by about 2". The advantage it has over the Tenor Trackless Arm is that it has a more traditional height adjustment mechanism where the tray moves only slightly closer to the desk as it is lowered.
NOTE: The Tenor Trackless Keyboard arm DOES NOT accommodate the hole pattern of Humanscale Keyboard Trays.
