Sold in pairs, these stackable stakes make it simple to create a raised bed. Just mark out the area, drive the 11" long stake corners in where needed, and drop 2 x 6 lumber (not included) into the brackets on the stake.
If you want the walls higher, stack the corner stakes on top of each other. Now fill the box you've just created with soil and you have an instant raised bed.
The brackets adjust to any angle between 60° and 180° to make a variety of shapes. A very simple way to make a raised bed. Made of fade-resistant ABS plastic.
