ABSTRACT:
A wrist rest support system for supporting a wrist rest beyond the edge of a working surface, including an extension clamp having a cantilever plate having a first end member proximate the working surface and a second end member, the second end member having a distal end cantilevered away from the working surface. Each end member has a separate longitudinal axis spaced laterally apart. The longitudinal axes are approximately parallel. A fastener for attaching the cantilevered plate to the working surface is connected to the first end member of the cantilever plate. The second end of the cantilever plate has a groove proximately perpendicular to the second axis. The groove is for receiving a sculpted portion of a base member of the wrist rest. A retaining member is disposed upwardly at the distal end of the second end member. The retaining member is for retaining the wrist rest on the second end member.
