Abstract
Abstract A ceiling tile replacing and positioning apparatus is disclosed in which a frustum-shaped frame is provided. An encircling flange on the larger base end of the frustum provides a platform upon which the ceiling tile may be rested. Pins project perpendicular to the flange to hold the tile in place. A handle including a sleeve which is pivotally and releasably attached to the frustum-shaped frame at the frustum smaller base makes the apparatus usable from various angles.
