The keyboard drawer is an economcal solution to proper keyboarding height. Many desks have a surface that is too high, causing the user to reach upward to use the keyboard. The keyboard drawer attaches under the work surface making keying and mousing more comfortable. The ball bearing slides allow for quick and easy storage under the work suface freeing up the desktop for other work. Perfect for use in reception areas. The DR drawer slides are designed to accommodate all CarpalRest ® keyboard platforms.
