Step 5. Attach the Planter Box
Place the planter with its open backside against the front face of the marker plaque, 1 1/2” from the bottom corner edges. Determine whether you want your planter oriented to the right or to the left side of the plaque. Use a carpenter's square to measure the vertical and horizontal placement of the planter's outside edges on the plaque. Clamp the planter to the plaque to keep it in place.
Transfer the vertical and horizontal measurements of the box to the back of the plaque by penciling in guidelines, using your carpenter's square to indicate the edges of the planter. Drive five 2” screws through the back of the plaque and into the edges of the planter, one in each corner and one along the bottom center.
