Of all the models in the collection, the 'Groove' perhaps comes closest to the famous design concept that less is more. The 'Groove' is the ultimate tribute to the 'no-nonsense' approach. No screws, clamps or bolts, except where absolutely unavoidable. The glass is slid into the mounting in an original but easy to operate manner. The 'Groove' is highly practical, but with two light slits in the side panels as a fun extra feature.
