Caution! The corners of our metal frames are carefully mitered to achieve a perfect fit and finish. Their edges are sharp, and should be handled carefully. Step 1: Drop hanging wire brackets into place and tighten their screws. Loosen two bottom screws shown. Step 2: Remove bottom rail, and slide frame contents out. Install your art, replace contents, tighten screws. Step 3: Insert spring clips spaced evenly between the backing and the channel it rests in. Put one wall bumper on each corner.
