This particular piece is a set of 2 each antique 2-1/4 concentric ring art deco style wrought steel nickel-plated door knobs mated to a nickel-plated wrought steel antique princeton design door plate manufactured by p & f corbin (new britain, ct) in about 1940. These knobs are beautiful, classy, and clean, and the door plates have their natural patina with the door plates measuring about 7-1/4" x 2-1/2". All lacquered and ready to go. Mounting to the wood surface is via screws through the door plate screw holes.
This set is provided with a set of high-quality 1 solid bronze #6 slotted wood screws. The screws will be raw bronze unless aesthetically required, then these screw heads will have a satin black finish to help them to blend into the darker door plate finish. Screw design: we only use slotted head design screws because they are historically accurate. Never use a phillips or other screw head types when installing historic antique hardware.Screw material: we use bronze because it is harder than brass and will not color like iron. Bronze screws are what was used on all of the best historic hardware installations. Screw length: we supply 1 screws because this is the average size that people request. Remember that the depth into the wood is less than 1 because the door plate thickness must be accounted for.
If you think you need longer or shorter screws please make a note when you place your order. Thickness of the plate, the door, the type and age of the wood, and the actual application all come into consideration when specifying your screw length. The longer the screw, the more bite the assembly will have in the wood. For french or double door installation. This item is made of nickel plated wrought steel.
