The Staccato Keyboard Arm from KV Waterloo is an ideal solution where storage depth is limited but an adjustable height keyboard tray is desired. The 14" track is short enough to permit installation in locations where a traditional full-length storage track will not fit, including many height-adjustable sit-stand desks. The patented "Lift-N-Lock" mechanism provides almost effortless height adjustment from 1.375" - 6.5" below the mounting point. The inclination or "tilt" of the tray can be adjusted from a negative inclination of -20° to +10° using an easily-accessed soft-touch knob. When fully lowered the Staccato offers approximately 9" of tray storage depth. Knee clearance is optimized, with the keyboard tray mount extending less than 0.75" below the tray.

The Staccato Keyboard Arm is equipped with plastic glides riding within a heavy-duty steel track. The Staccato is manufactured using recycled materials and is designed for disassembly and recycling.

The Staccato can be paired with many keyboard trays but please note that tray depths over 9" will still project about 2". Suggested fully storable tray options are listed in the Accessories section of the "Price & Availability" section below.

For situations where there is insufficient space for a 14" track the Tenor Trackless Keyboard Arm may be a solution.

The Tempo Dual Monitor Arm from KV Waterloo is a versatile, stylish monitor arm made of diecast aluminum for dual monitors ranging in total weight from 15 to 40 lbs. This arm uses a gas spring mechanism for smooth movement in all directions with 14.5" of vertical range and a maximum horizontal extension of 26.75" (from back of monitor mount to VESA plate). The lower arm is fixed at a 45° angle, ensuring that arm movement is not obstructed by other items on the desktop. The counterbalance on the arm has a numbered weight gauge (15 to 40 lbs) to provide an indication of the current counterbalance weight. Cable management is included, consisting of a hollow plastic tube and cable clips, and the Quick Connect Adaptor simplifies mounting and swapping monitors when needed. Maximum monitor size is 24" (diagonally). The maximum physical width the arm can accommodate is 23".

The 7760AS model comes with both clamp and grommet mounting systems.

The HDPE Mini Keyboard Tray from KV Waterloo is ideal for situations where storage space for keyboard and mouse is highly restricted. With a width of just 19.4" and depth of 9.4", the tray is capable of accommodating virtually any keyboard. The rigid 0.5" thick tray is formed from HDPE (High Density Polyethylene) which is fully recyclable and features non-slip strips for secure keyboard placement. The included pivoting mousing surface is formed from 0.25" thick phenolic resin and includes a repositionable mouse guard and cable manager. The 9" diameter mousing surface is positioned 1.34" below the keyboard surface can be mounted to the right or left and pivots below the tray for storage. Included with the Mini Keyboard Tray is a removable gel-feel foam palm rest. The Mini Keyboard Tray features a universal mounting pattern for easy attachment to any KV Waterloo keyboard arm.

The compact dimensions of the HDPE Mini Keyboard Tray make it a perfect companion for the Tenor Trackless Keyboard Arm which was designed for the same highly restrictive space limitations. This combination of products offers the ultimate in compact keyboard storage.

The Harmony Tray from KV Waterloo incorporates a mousing surface which can be pivoted through an arc toward the body on either the left or right side. The mousing surface easily slides to the right or left as required or can even be fully stored beneath the keyboard. Both left and right positions offer eight forward-angled settings which let the mousing surface be moved through an arc towards the torso, positioning it for the most ergonomic benefit. The ease with which the mousing surface can be re-positioned makes this tray a good selection for someone who has limited width for tray storage (with the mousing surface centered for storage the tray is only 23" wide) but who wishes to spread their mouse use between both left and right hands. The roughly 8" by 9" mousing surface will accommodate most mice but may not be suitable for use with some of the more specialized ergonomic mousing solutions with larger footprints as it has a 1/8" ridge along the side and back edges which limits the possible range of mouse movement.

The Harmony Tray has raised rubber anti-skid pads to prevent the keyboard from moving and is only compatible with keyboards at least 15” in width.

The Harmony Tray is thicker than some other trays due to the inclusion of the sliding mousing surface. As a result it does elevate the keyboard higher off the keyboard arm. Individuals who wish to keep the keyboard and mouse as low as possible without interfering with the movement of the legs may wish to consider other options which present a lower profile.

The Phenolic Keyboard Tray with Swing-Out Mouse Tray from KV Waterloo lets one create a wide variety of custom configurations for their input devices. The Keyboard Tray portion is 20.5" wide at the front and tapers slightly narrower (20") at the back. A depth of approximately 10" means the tray is large enough to accommodate even the largest keyboards with integrated palmrests. Two anti-skid grip strips are positioned to keep a full-size keyboard secure on the tray surface. The tray ships with a detachable Foam-Gel palm rest which reduces the maximum keyboard depth to 7", still enough space for most standard keyboards.

The detachable mouse tray provides an 8.5" diameter mousing surface and features a unique tilting and rotating pivot mount which can be used to position the mouse tray either level with the keyboard tray or at 0.5", 1.25", 1.5" or 2" above the keyboard tray. The inclination or tilt of the mouse tray can also be adjusted, independent of the keyboard tray orientation, to any angle from all height settings. A repositionable mouse guard with cord clip ensures that the mouse stays in place. The pivot permits the mouse tray to be swung into the position which best meets the ergonomic needs. The range is a full 360° at the highest settings and reduces to 90° as the elevation is lowered to level with the keyboard tray. The mouse tray attaches to the keyboard tray via a clamp mount which can be secured at any point around the edge of the tray, further expanding the customization options as it can be easily reconfigured between left and right positions.Note: The dimensions of the clamp may limit the use of very wide keyboards (such a the Microsoft Natural Ergo Keyboard 4000). As well, with the palm rest installed, the mouse tray mounting clamp must be positioned about 2" further from the body as the palm rest extends the full width of the keyboard tray.

This arm is similar to the standard Duet arm but offers storability along a 23" (58.4 cm) storage track, has slightly less range of movement and uses a paddle instead of a T-Pull for height adjustment.

Make your own custom tray or purchase our special 12" (30.5 cm) deep Duet Trays (in the Trays category). The 39" (99.1 cm) tray is wide enough for a keyboard, mouse, phone and notepad - a complete desk available for use while sitting or standing.

The Concerto Height Adjustable Arm from KV Waterloo is a stylish, easy-to-install pole-style monitor arm. This double extension arm swivels about the base 360°, with the double extension mechanism allowing forward and back movement up to 24". The 30" pole allows ample height adjustment as needed. Mounting options include both desk clamp and grommet hole configurations, with potential for addition mountings for panel, wall, and slatwall setups (not included). This unit also comes with cable management to hide unseemly cables, and fits monitors complying with VESA 75mm and 100mm hole patterns.

The Volante HD42 Desktop Sit-Stand Workstation from KV Waterloo comes bundled with a sturdy dual-monitor clamp mount monitor arm and can be placed on virtually any fixed-height desk to provide an instant dual monitor sit-stand solution. With a 42" wide work surface the HD42 version of the Volante is able to accommodate dual 27" monitors, monitor arms (single or dual), laptops with secondary monitors, or even an Apple iMac. 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 work surface from 6.2" to 20".

A right hand paddle release lets the height be adjusted 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 HD42 provides a highly stable work surface 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 42" 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°) so each worker can adjust the keyboard inclination to provide for optimal neutral alignment of their wrists. Three 2" grommet holes at the rear of the upper platform can serve as cable guides as well as for attaching a monitor arm should greater elevation be required.

The bundled dual monitor arm is a "clamp-mount" that attaches over the rear edge of the worksurface. It can elevate the VESA mounting point for the monitors up 16" above the mounting surface. Each monitor mount is equipped with tilt and pan and the 3-section crossbeam also articulates to accommodate a cockpit-style workstation layout.
