Description:

Package and Size: 12 x Corner Brackets, each corner bracket size: 18 x 20 x 20mm / 0.7" x 0.78"x 0.78"(L*W*T), Thickness: 3mm / 0.11", Hole Diameter: 5.5mm / 0.21".. Material: Our brackets are made of good quality aluminum with a black baked enamel surface to ensure rust resistance and durability, the brackets are oxidized to protect the aluminum from oxidation.. More Stable: The design of the vertical corner connector allows for a 90-degree right-angle joint, which is highly helpful when constructing square or other rectangular structures. The overall design with a flattened surface means that the connector has a larger contact area with the aluminum profile, providing a more stable connection.. Application: These right angle brackets are versatile for constructing all sorts of industrial aluminum frame structures, 3D printers, CNC routers, CNC laser cutters, and diving into robotics projects. Plus, they are woodworking machinery covered and setting up fish tanks too..
