The lightest of the Esto Aluminum frame systems, the 3/4" square tubing has a .050 wall thickness. Working in conjunction with our 3/4" molded nylon connectors, this type of anodized aluminum tubing is perfect for lighter, smaller design projects. Ideal uses include small bird aviaries, image framing systems, lighter retail display systems and table top displays. These tubing profiles can be ordered in 8 ft. stock lengths or cut to size. Standard colors include anodized clear or anodized black.
