Building Materials and Construction Components Design Ogro 8115 Door Handle by DORMA The OGRO 8115 door furniture range demonstrates how everyday objects can be reinvented without losing their essential utility. The clearly defined radii contrasted with the full radii element make the product more ergonomic. The overall dimension is adapted to the human motion sequences. The range encompasses standard, security and pull handles, door knobs and accessories of aluminum and stainless steel. The face surface texture is grinded horizontally. The pull handle range builds up on a system of 10 parts and a maximum length of 2400 cm.
