Select a location for your flower box. Hold the box up to the wall to ensure it is the proper distance from your window or other wall features, marking the outline of the box with a masonry pencil or chalk.
Position and mark your brackets. Spread the brackets evenly across the space where the flower box will hang so the box is properly supported once installed. Mark the screw holes for each bracket.
Put on safety glasses or other eye protection, and drill holes for your screws at the positions you marked. Make sure the holes are in the brick and not the mortar, and use a masonry bit to drill them 1/4 inch to 1/2 inch deeper than the length of your screws.
Attach your bracing brackets to the wall: Insert lag shields into the holes you drilled, tapping them in with a hammer until they are flush with the brick surface, and then secure the brackets using lag screws.
Position your flower box and attach it to the brackets. Drill holes in the bottom of the flower box if necessary, and use lag bolts to attach the box securely.
