From industry leader, Tradco Hardware, this antique brass flush bolt is specially designed to be mortised into the edge of a French door, making it invisible when the door is closed. It is made of solid, hand-aged brass, making it the perfect complement to their range of antique brass door lever handles. It can be installed facing upward into the frame or downward into the floor. A coordinating flat keeper and recessed screws are supplied for a cohesive look.
