This handy keyboard/shelf is made from 16 Gauge steel with a Satin black finish.
The mouse pad includes a satin textured pad finish surface that can be mounted on either the right or left side. The keyboard shelf slides are ball self lubricating ball bearing and include a positive click stop upon extension which prevents the shelf from unwanted retracting.
The two shelf surfaces available are the retractable lower shelf which accommodates a standard "qwerty" (16" or smaller) style keyboard or the upper shelf which accommodates a wider "101 style" keyboard. The upper surface also includes a front lip and large surface area for monitors or other hardware.
The shelf includes both 10-32 and 12-24 mounting screw kits which are included to allow mounting on either thread pattern.
Measurements are: 14" collapsed Depth, 19.25" Width, 16" and 19" Keyboard and Shelf Width, 3.5" Height. Can hold up to 50 lbs.
