This 4" x 10" Center Lock has an extended throw that latches through the bottom door rail into the floor, and a strike for the horizontal throw from adjacent Center Lock. It is completely activated at a comfortable distance above the floor utilizing a built-in Adams Rite® 1860-02 Lock with a modified extension rod allowing the throw to enter the floor. A small edge channel that travels down from the Center Lock to the bottom rail conceals the extension rod. It includes an 8" (203 mm) back-to-back "D" Handle, a Thumbturn on the inside, and a Keyed Cylinder on the outside.
