Abstract: A system for easy installation of the accessory on a building comprising a clip and an installation tool is disclosed. The clip can accept an accessory (e.g. a light string), and reversibly engages the tool. The tool can be conveniently mounted on a elongated handle so the user can work without ascending and descending a ladder. The clip comprises structures to secure it in the tool while the clip and accessory are being positioned. The clip is configured to the flexible and to provide a bias force that maintains the clip and accessory in position once installed on the building member. Once the clip is in the position, the tool can be disengaged from the clip and a new clip inserted in the tool. The invention for example is useful for easy lifting and placement of a string of decorative lights on a building facia or comparable structure.
