Abstract: A support base system is provided for holding architectural panels in adjustable height positions. The support base system comprises an elongated U-shaped support base with a channel extending from its top surface. A U-shaped insert is positioned in a bottom portion of the channel. Locking angles are positioned along the top surface of the support base with one leg having a series of ribs extending into the channel. A series of set screw holes along at least one side of the support base with set screws therein for communication with the locking angles are used to adjustably abut the locking angles to the panel. The panel is positioned in the channel a desired depth and the set screws tightened to securely hold the panel.
