The Ovation provides the largest range of movement of any articulating keyboard arm on the market today (other than sit-stand arms) in a low profile, durable design. It uses a near-effortless patented "Lift-N-Lock" counterbalance mechanism to adjust an attached tray from 7.0" below to a full 3.8" above (17" track version: 5.8" below and 2.6" above) the mounting point. A Height Indicator Gauge makes adjustment easy to measure. The inclination, or "tilt," of the tray can be adjusted from a negative inclination of -15° to +10° using a large Dial-a-Tilt knob that includes an "Inclination Gauge" (allowing accurate repositioning at the desired angle).

The sleek, low profile design provides excellent clearance for the legs and knees. The arm swivels 360° from the track mount for side to side movement. Three track lengths are available. The 17" (8634D17) model can be deployed where mounting space is restricted but has a more limited range of height adjustment and does not permit full storage of trays. The 23" (8624D23) storage track offers the full range of height adjustment and permits full storage of trays up to 11" in depth. To fully store an Extra-Deep (13") or Mouse Intensive Tray underneath the desk, an Extended Track (8624D28) version is also available with all the features of the 8624D23 but equipped with a 28" track. All Ovation models accept all standard trays and use a high quality steel ball-bearing storage track that has a much longer lifespan than a glide track.

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.

Individuals using sit-stand desks 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.
NOTE: The Tenor Trackless Keyboard arm DOES NOT accommodate the hole pattern of Humanscale Keyboard Trays.

The Ovation Sit-Stand Keyboard Arm by KV Waterloo offers a range of height adjustments to accommodate sit-stand workstations. Using a patented "Lift N Lock" counterbalance mechanism the arm allows an attached keyboard tray to be positioned at heights ranging from 8.4" above the mounting point to 5.6" below it. The 23" storage track enables most keyboard trays to be fully stored beneath the desk when not in use. The curved neck (see the first image on the Detailed Specifications page for an illustration) allows individuals to be comfortably close to the desk when seated and when standing.

All Ovation Keyboard Arms include a low profile mounting plate for the keyboard tray. The mounting plate is connected to a "Direct Drive" dial tilt mechanism that includes an inclination gauge. By simply turning the dial, and watching the inclination gauge, one can easily set up their workspace to position their keyboard at the preferred inclination, from a positive inclination of +10° to a flat 0° to a negative inclination of -15°.

NOTE: On a standard 28.5" high desk (measured from the underside of the desk), the Ovation Sit-Stand Keyboard Arm will provide enough height for proper "standing" positioning of the keyboard tray with no inclination for those under 5'5". For individuals standing between 5’5” and 5’7”, this product can still be suitable but will require a negative inclination on the tray (which brings up the tray worksurface accordingly). This arm is also suitable for individuals under 5’ 7” who are using a “lean-into” seat which puts them in a position between sitting and standing. If negative inclination on the tray is acceptable, those between 5’ 7” and 5’ 10” may also be able to use this product to meet their needs. Taller persons may be accommodated by raising the mounting height through use of products such as the Raise-Its. Of course, monitor elevation must also be considered when moving to a standing position.

The Duet Sit-Stand Arm can be employed to create a sit-stand workstation suitable for a wide range of heights. It is able to be lowered a full 6.5" below and raised to 12.5" above the mounting point.

The Duet Sit-Stand Arm features a convenient tilt control release permitting ±15° of worksurface adjustment and a field adjustable coil spring which adjusts for load counter balance. Height adjustment is easily accomplished by using the T-pull release to disengage the lock, then raising or lowering the tray to the desired working height. The slim (only 0.75" wide) dual arm (with crossbar) design ensures that the knees and legs have plenty of room - and far more than any single central support arm. The Duet Sit-Stand Arm is available in four widths, each offering progressively more width between the tray support arms. For optimal workspace and knee clearance the wider models are generally recommended unless there are space restrictions.

The Duet Sit-Stand Arm easily accommodates custom-built trays or you may choose to select the appropriate Duet Arm Custom Tray to create a complete sit-stand workstation. The 39" tray is wide enough for a keyboard, mouse, phone and notepad - a complete desk available for use while sitting or standing.

When installed on an average height, 1" thick worksurface (28.5" from the floor to the underside of the desk), this arm can elevate an attached tray to 41". By taking advantage of the negative inclination option and angling the front edge of the tray upwards, the potential height range can be extended slightly higher (42" - 43"). Note: For taller individuals it may be possible to achieve greater elevation by employing a product such as RaiseIts to raise the desk, thereby raising the mounting point. If this is not practical there are many other options available to create sit-stand workstations for taller persons.

While the Duet Sit-Stand Arm does offer a wide range of height adjustment, it accomplishes this with the sacrifice of storability. If the ability to store the tray below the desk is necessary there are other options which may be suitable. Please call and speak with a Customer Service Representative should this be the case.

The Allegretto Height Adjustable Table Base from KV Waterloo is an extra-smooth and quiet electric adjustable width table base capable of supporting table tops from 48" to 90" in width and 24" to 30" (or deeper) in depth. It is available in 2- or 3-leg configurations. Easy to assemble in less than 30 minutes, the Allegretto has an adjustable height range from 23.9" to 49.5" with an adjustment speed of 1.6 inches per second. In addition, a six-button programmable switch with 4 presets facilitates the setting of pre-determined heights to individual needs. The base can also lift weights up to 264 lbs and has built-in Anti-Collision protection in the event that the table collides with a fixed object while moving up or down, in which case it will stop and reverse direction.

The stylish design adds a modern clean look to any office environment, largely due to the absence of a lower crossbar. This base is also UL, CSA and CE certified with a 5 year mechanical and 2 year electrical warranty.

NOTE:DIADEM, Conset or iMovR Table Tops can all be used with this base, or you may provide your own custom-made or pre-existing table top.

The Ovation Keyboard Tray System combines the proven quality and exceptional adjustment range of the Knape and Vogt Ovation Leverless Arm with the durability and low profile of the ABS Plastic Keyboard Trays. Multiple widths and depths of tray are available, permitting individuals to select the tray that will best accommodate their keyboard and mousing devices while still fitting within the space constraints of the workspace.

The high quality Ovation Leverless Arm offers an exceptional range of elevation adjustment that can meet the needs of virtually any seated individual. The low profile, durable design uses a near-effortless patented "Lift-N-Lock" counterbalance mechanism to adjust an attached tray from 7" below to a full 3.75" above the mounting point. A Height Indicator Gauge makes adjustment easy to measure. The inclination, or "tilt," of the tray can be adjusted from a negative inclination of -15° to +10° using a large Dial-a-Tilt knob that includes an "Inclination Gauge" (facilitating easy repositioning at the desired angle).

The sleek, low profile design provides excellent clearance for the legs and knees. The arm swivels 360° for side to side movement and the 23" storage track allows one to store the arm and tray out of the way when not in use. The high quality steel ball-bearing storage track has a much longer lifespan than the more common plastic glide systems used by most manufacturers and ensures years of smooth, virtually effortless storage movement.

The ABS Plastic Low Profile Trays are just 0.375" thick and are free of any surface obstructions, providing the greatest flexibility in terms of arranging keyboards, mice, palm supports, etc. The rear edge has a Keyboard Guard which serves to keep both keyboard and mouse from slipping off the back edge when the tray is put in a negative inclination. It also protects the keyboard from the underside of the desk when stowing the tray (if the tray is too high, the "guard" will catch on the desk, protecting the keyboard from possible damage. Lastly, notches in this guard provide cable management for the keyboard and mouse.

Note: Deeper (13") trays project about 2" with the standard Ovation model. If there is sufficient depth to mount a 28" track the Ovation Long Track Keyboard Tray System will provide complete storage of the deepest trays.

The Volante Desktop Sit-Stand Workstation from KV Waterloo can be placed on virtually any fixed-height desk to provide an instant sit-stand solution. It will fit any desk with a depth equal to or greater than the 23.2" footprint depth. This well-engineered product provides a full 13.8" of height adjustment range. Keyboard height will adjust from roughly 1" to 14.8" above the surface and the upper worksurface from 6.2" to 20". Simultaneously activating the left and right paddles facilitates height adjustment to any point throughout the entire lifting range. Gas cylinders provide lift assistance to minimize the effort required to make adjustments and the unique locking system offers infinite adjustment throughout the entire range. Regardless of the height, the Volante provides a highly stable worksurface and keyboard tray, with no detectable wobbling or movement of the mechanism. The cantilever design of the Volante means that as it rises it also moves out and towards the body, requiring one to step back and away to accommodate the new positioning.

The upper platform for monitor, tablets, or documents is 35.4" wide by 15.7" deep; while the keyboard and mouse tray is 26.4" wide by 13" deep. The keyboard tray features a tilting mechanism (±10°) that can be used to adjust the keyboard inclination and provide for optimal neutral alignment of the wrists. The 2" grommet hole at the back of the upper platform can serve as a cable guide as well as for attaching a monitor arm should greater elevation be required.

The Ovation Short Track Keyboard Tray System combines the proven quality and exceptional adjustment range of the Knape and Vogt Ovation Leverless Arm with the durability and low profile of ABS Plastic Keyboard Trays. Multiple widths and depths of tray are available, permitting users to select the tray that will best accommodate their keyboard and mousing devices while still fitting within the space constraints of the workspace.

This "short track" (17″) version of the Ovation Leverless Arm has a good range of elevation adjustment that can meet the adjustment needs of most seated individuals. The shorter track means that it can be deployed in situations where there is insufficient space for mounting a longer 23" track. In order to better accommodate tray storage with a short track this arm is equipped with a shorter neck than the standard 23" model. However, even with the shorter neck trays will still project, even at the lowest setting that offers the maximum storage depth. A 9" tray will still project about 2.5", an 11" will have about 4.5" of tray exposed, and a 13" deep tray will project about 6.5".

The low profile, durable design uses a near-effortless patented "Lift-N-Lock" counterbalance mechanism to adjust an attached tray from 6.1" below to a full 2.3" above the mounting point (i.e. underside of the mounting surface). A Height Indicator Gauge makes adjustment easy to measure. The inclination, or "tilt," of the tray can be adjusted from a negative inclination of -15° to +10° using a large Dial-a-Tilt knob that includes an "Inclination Gauge" (allowing the user to reposition at the desired angle).

The sleek, low profile design provides excellent clearance for the legs and knees. The arm swivels 360° for side to side movement and the 17" storage track allows tray storage when not in use. The high quality steel ball-bearing storage track has a much longer lifespan than the more common plastic glide systems used by most manufacturers and ensures years of smooth, virtually effortless storage movement.

The ABS Plastic Low Profile Trays are just 0.375" thick and are free of any surface obstructions, providing the greatest flexibility to the user in terms of arranging keyboards, mice, palm supports, etc. The rear edge has a Keyboard Guard which serves to keep both keyboard and mouse from slipping off the back edge when the tray is put in a negative inclination. It also protects the keyboard from the underside of the desk when stowing the tray (if the tray is too high, the "guard" will catch on the desk, protecting the keyboard from possible damage. Lastly, notches in this guard provide cable management for the keyboard and mouse.

Note: Due to the potential storage issues where there is limited space for track mounting the more specialized Staccato and Tenor tray mounting systems might be of interest. These offer alternative mounting that permits slightly greater storage than the Ovation Short Track Keyboard Tray System.

This version of the Momentum Arm swivels in two locations. The 'elbow' can swivel 45° to either left or right, while the 'shoulder'(where it mounts to the underside of the track) will rotate the usual full 360°. This makes this unit ideal for corner applications, or any workstation where an 'off-centre' mount of your keyboard arm is required (e.g. no suitable mounting in the ideal location). Using the dual swivel capabilities it is possible to position the tray up to 5.5" to either the left or right of the track mounting point.

The 23" storage track lets you get the arm out of your way when not in use. It has the Lift and Lock height adjustment, and a soft touch knob to tilt the platform to the desired angle. Accepts all standard trays.
