Spline is the single planter with a circular shape whose vertical slatted work strongly characterizes its design, giving rhythm to the metal surface. A design object in perfect balance between modernity and tradition. Spline is produced without size limits, both for outdoor and indoor installations, with or without wheels. The pivoting wheels, when present, are never visible. Spline is also available in extra large versions with special internal reinforcements that allow the insertion of large, tall plants. In the very large and low version, it forms a real rounded modular flower bed. In this case, it is supplied both with a steel base and a PVC bottom, and with a polyethylene bottom and water retention panels.
