The Delamain DK37C Reeded (Concealed Fix) Door Knob on Rose Satin Nickel is a beautiful ball-shaped knob with thin lines scored into the surface giving it a reeded appearance, often also known as a beehive knob. The door knob has concealed fix roses and screws are supplied. The finish of a door knob really does change the character of it quite dramatically, as the Delamain plain door knob in satin nickel shows, as it can look stunning in a more modern property simply because of its colour.
