Gardener's Supply CompanyRaised Garden Bed Lifetime Inline Connectors | Outdoor Rustproof Aluminum Planter Box Reinforcement Brackets with Screws & Plastic Cap | 10" H (Set of 2) - Black

Just what I needed. The aluminum extrusion is a little thin, but it did just what I wanted it to do. My raised beds are much stronger withthe extension connectors in place. Thanks for having exactly what i needed for my project.

Great concept. However, there isn’t a 2-inch board without some curve in them, making the installation more difficult than if I had just used wood bracing. I literally had to beat the boards to fit. Ugh, what a nightmare.

Pictures are from early May, early Mother’s Day gift that husband built. One thing he noticed when assembling, was that the wood that went in the middle, had to be cut 1/2-1” shorter than the wood on the ends, or it bowed out. He also ended up drilling 2 or 4 extra holes in the extenders, for the middle of the planter, so it would grab onto the wood properly, since he used 2 pieces of 2”x6”. Other than those small hiccups, these extenders are exactly what I needed. A bit pricey, but I couldn’t find any other company that sold them. This span was 8’9”, and I wanted a custom built planter to fill the space. I am very happy with how it looks.
