Use the Workrite® Pinnacle Arms to mount Workrite® Platforms to the work surface.
Available in two track lengths. The 22" track will require 22" (56cm) depth and 6" (15cm) of width for mounting under the desk (from the front edge going straight back) and will allow complete storage of the platform under the desk when not in use.
The 17" track may be needed for smaller desks and requires only 17" (43cm) depth and 6" (15cm) width for mounting under the desk. This platform will not completely store under the desk, but will extend 4" (10cm) when pushed all the way back.

The tilt range is -15° to 10° with no-knob, no-lever, lift-n-lock one-touch height adjustment. Independent height and angle controls. Height range goes from level with the desk top to 6" (15cm) below worksurface. Swivels 360° for easy positioning and storage. The non-intrusive, low profile track provides maximum knee clearance and smooth, consistent operation.

Some popular platforms used with these Pinnacle Arms are the WRUB188-25, WRUB187-25 and WRB2180S-25.
