Abstract
A ceiling sign installation pole having a slot for carrying an anchor and an intersecting slot for permitting the exiting of a hook hung from the anchor. The installation head has a flat surface with two bumps for lifting adjacent ceiling tiles out of the way during the installation process. The walls of the exit slot bevel outwards towards the bottom of the installation head. Additional slots may be provided for different sized anchors. A flexible joint is used to connect the installation head to an elongated pole.
