         9 . The invention of  claim 8  further including a second channel member and wherein the plurality of sub-frame members includes a second sub-frame member, the second channel member fixedly engaged with the bottom surface of the desktop and wherein the desktop and second channel slideably engaged with the second sub-frame member. 
     
     
         10 . The invention of  claim 9  wherein the second channel member includes a first set screw, engaged therewith, for releaseably engaging the second sub-frame member. 
     
     
         11 . The invention of  claim 10  wherein the second channel member includes a second set screw, the second set screw for releasably engaging the second sub-frame member. 
     
     
         12 . The invention of  claim 11  wherein one of the first or the second set screw has a knob and the other of the first or second set screw has a tool engaging head.
