Abstract: Disclosed is a stanchion support device which comprises a washer having secured thereto a threaded column. About the threaded column is a toroidal collar of hard rubber. Placed over the threaded column is a metal sleeve. Threaded onto the threaded column is a nut which forces the metal sleeve downward against the rubber collar and pulls upwardly on the washer. The combined force of the sleeve and washer causes the rubber to expand. When this combination is placed within a cavity, such as may be defined by a cup placed in a cement floor, the rubber is so dimensioned as to engage the cup wall, thereby securing the stanchion support device within the cup. A stanchion may be secured to the nut. The stanchion itself may be provided with one or more L-shaped brackets which are freely rotatable thereupon and retained from sliding down the stanchion by a support, such as a ring, welded to the stanchion. An enlarged head of the stanchion prevents the removal of the bracket off the top of the stanchion.
