Abstract: A tripod supported platform has mounted thereon a plurality of arms, each being extensible against the force of a tension spring. The distal ends of the arms are releasably engageable with the rim of a pail or like container for holding the pail on the platform. The arms are removable and the depending brackets adjacent one end of a paint tray may be hooked under the edges of the platform with the other end of the tray overhanging the platform. A retainer is attachable slidably to the platform to permit seating of the tray on the platform and then slidable against the one end of the tray to force the brackets under the platform and securely support the tray on the platform, and to provide for securing different length trays on the platform. One of the tripod legs is pivotable under the platform for storage.
