Abstract: A partition system includes connecting tubes having rectangular apertures and cooperating with panels provided with upwardly directed tabs insertable within the apertures for supporting a plurality of the panels. A retention assembly attachable at the top of each tube includes a plate horizontally insertable into slots in two adjacent panels and carrying a vertically adjustable threaded member releasably engageable with the top of the tube to apply a biasing force urging the panel tabs upwardly into the tube apertures to secure the assembly of tubes and panels. The threaded member is subsequently operable in reverse to apply an opposite force between the tube and panels to facilitate separation of the panels from the tube.

Abstract: A partition system post cover includes an elongated cover plate serving to mask a support post between two adjacent panels. Edge channels on the panels are provided with slots and fastener assemblies carried by the cover plate include spring arms insertable into selected edge channel slots to securely yet removably retain the cover in a position overlying the post. The cover plate may be configured to accommodate various angular dispositions between adjacent supported panels to insure full masking of the support post.
