Abstracta’s 13mm (½-inch) tube diameter system provides a lightweight modular display offers the versatility of its design that makes it among the most popular choices for artists in sculpture, pottery, jewelry and other 3D works. Artists also appreciate the ease in putting the display together for a limited-time exhibit and disassembling it afterward to take to your next showing. You will need a nylon mallet to secure the tubes, and the Abstracta Disconnect Tool and Extractor Rod for taking 13mm units apart.
