Abstract
Abstract This disclosure relates to a desk assembly in which a support such as wall hung brackets mounts an open top bin in a desk top. The desk top is slidably fixed to the support through opposing Ushaped channels having ball bearings therebetween. The bin is supported beneath the desk top so as to permit access thereto by sliding the top between alternate positions.
