Is this knob solid brass or brass-plated?

It is described as a brass knob, so the body is brass rather than a plated base metal. Brass develops a patina over time and can be polished back to a bright finish.

What does the 1 3/8-inch measurement refer to?

It is the knob's projection, the distance it stands out from the cabinet face. Check clearance against adjacent doors and drawers before ordering.

Will the rosette cover my existing screw holes?

The Classic rosette sits behind the knob and covers the mounting area, which helps hide marks from an old pull. Measure your existing hole spacing to confirm the rosette spans it.

Does it come with mounting screws?

Cabinet knobs of this type normally ship with a mounting screw. Confirm the screw length suits your door or drawer thickness, since thicker fronts need longer screws.

How does it compare with a plain round brass knob?

The Deco knob adds a geometric stem and a separate rosette, so it looks more designed than a plain sphere. It costs more work to install but gives a stronger period look.

How do I keep the brass finish looking new?

Wipe with a soft damp cloth and dry it. Avoid abrasive cleaners, which can dull the finish, and polish occasionally if you want a bright rather than aged look.
