 Use a rubber mallet to tap a pre-assembled 2' END PANEL into the open channel of a CORNER, positioning it so the CROSS 

SUPPORT sits under the PLATFORM SUPPORT on the 8' side panel as shown in 

Figure 2

. Ensure END PANEL is fully seated and 1/8" 

above the top of the CORNER, then secure with PHILLIPS SCREWS as shown. Repeat to attach the remaining 2’ END PANEL to the 
other end.

 Place the remaining 8’side panel on a flat surface. Carefully guide the ends of the 2’ END PANELS of your partially assembled 

box into the open channels of the CORNERS. Secure with PHILLIPS SCREWS. Once all panels are attached, stand your Planter 
Box right side up and tap a CORNER CAP into the top of each aluminum CORNER.

 Install the 3 CROSS SUPPORTS to and under the PLATFORM SUPPORTS as shown in 

Figure 3

. Secure with SCREWS from the 

top.

 Insert the cedar FLOOR PLANKS, leaving small gaps between them (this will allow water to drain). Then, insert the FABRIC 

LINER. 

Filling and Planting

Fill your Planter Box with a lightweight potting mix. Do not use a heavy garden soil as that may overload your planter. Add 
some organic matter, such as compost and a slow-release fertilizer for best results. You're now ready to add your plants!
