The Ikea Lack Table Supporter helps extend the durability of your Lack table by minimizing damage from oscillation, e.g. from machines that create oscillations such as 3D printers. The outer holes are designed for standard #5 x 1" wood screws, and are positioned to frame the inside frame of the table for added strength. Adding secondary attachment with superglue on the contact surfaces helps to further secure the supporter. The screws on the leg sections are special positioned so that they do not interfere with each other for easy installation.
