Table base features an easy-to-operate release bar that lets you reposition your tabletop vertically for space-saving storage when it's not being used. Rubber bumpers protect your table from scratches when nested. Four heavy-duty casters with two that lock allow you to easily reconfigure tables as needed. Standard ganging clips allow you to quickly connect additional tables side-by-side or back-to-back. Table base is designed for 24" x 72" Special T tabletops (sold separately).
