Our levers are designed for constant use. Pushed, turned and bumped over and over again every day – whether in private homes or commercial buildings, government offices and cultural centres. From the curve of a handle, to the 21 ball bearings that roll against each other behind our lever roses, to the hardworking materials they are produced in, we have always seen every component of every design as having equal importance in the creation of the whole. Both internally and externally, every detail of every d line lever handle is rigorously tested for seamless functioning so that it endures. Then, assisted by the most cutting-edge machinery in our field, each is expertly crafted by hand.
