This product has been discontinued.
Description
Ergotron 33-421-085 WorkFit-SR positions a complete workstation within
the footprint of your desktop without protruding into your space. It
clamps to the rear of most surfaces, converting any tabletop into a
healthy sit-stand desk.
This is a premium furniture retrofit solution, featuring refined
aesthetics and superior material construction. When in the seated
position, the thin worksurface always stays close to your desktop. The
all-aluminum composition is extremely sturdy, allowing for easy,
handle-free height adjustment.
Short Surface models are only recommended for desktops that are 24"–30"
deep (61–76 cm).

Benefits
This model is optimized to accommodate a single, heavier display
Premium aesthetics and sturdy construction: all-aluminum worksurface, bow and pivots
Worksurface/keyboard tray stays on top of the desktop, never intruding into your space
A “Short Surface” allows this WorkFit-SR to be installed in space-constrained work areas where the desktop is only 24"–30" deep (61–76 cm). Note that this may compromise focal distance between screen and operator
Configuration flexibility makes WorkFit-SR well suited to taller users: worksurface can lift higher than other WorkFit models; monitor pivots can be installed at tall-user heights
Spacious worksurface accommodates any keyboard and mousing device with plenty of room for other desktop items
Internal cable management hides cord clutter; includes pre-installed USB cable for easy connectivity
Five-year warranty: tested and guaranteed! Proven lift technology is reliable through thousands of adjustment cycles
