Customize your space with the M Brace! The M Brace is an innovative new way to create raised garden beds. Each brace is about 10" tall and 9" wide, allowing you to make a raised bed 12"-14" high. Slide any standard 2" lumber (actual width is 1.5"-1.75 ") into the braces and you are ready to plant. Try stacking two 2"x6" boards on each side, or three 2"x4" boards. Maybe you want to use one 2"x12" board on each side. You get the idea! The best part? YOU decide the length and width that is just right for your space. 100% recycled metal, made in the USA! You can customize your garden space in just minutes with our many unique designs and choose the length and width that work for you. .
