2×4 Planter Box Plans



The first step of the project is to build the side panels for the 2×4 planter box. Therefore, cut all the components at the right dimensions, as shown in the diagram. Lay the horizontal cleats on a level surface and then attach the vertical slats. Align the slats at both ends so that the cleats overhang the panel 1 1/2″ on both sides. Drill pilot holes through the slats and then insert 2 1/2″ screws into the cleats. Leave no gaps between the slats.



Assemble the other 2 panels for the planter box. Use the same techniques described above to assemble the panels.
