Add durability, sophistication, and security when you install lockable flush bolts on your exterior doors. Part of the range of satin chrome door hardware from Australian supplier, Tradco Hardware, this bolt is made of tarnish-resistant, chrome-plated brass - which is gently hand-brushed for a satin finish. It is specially designed to be mortised into the surface of the door, providing a sleek, professional finish. Each one comes with two keys included - these can be keyed alike or differently on multiple orders. Specify your preference in the comments section at checkout.
