Passage: Passage door hardware has no locking mechanism. Both the interior and exterior handles are always free making it perfect for hallways, closet doors, and anywhere else a lock isn't needed. Passage door hardware can also be used in conjunction with a deadbolt to secure a back door or entrance. Features: Constructed of solid brass for durability and dependability Installs easily with all necessary mounting hardware included Covered by Baldwin's ADA compliant 28 degree latch ensures easy operation Product Technologies: Solid Forged Brass Construction: All Baldwin hardware begins with raw bars of solid brass which are heated, and pounded into specially made dies—producing a stronger, more substantial product. The difference between lesser metals and heat forged brass is noticeable the minute you hold it in your hands—solid brass is heavier, smoother, and naturally resists corrosion. Finishes™: Baldwin's multi-patented Finishes™ provide unprecedented protection against the effects of weather, normal wear and tear, and even the rigorous test of coastal salt air. By adapting the vapor deposition processed used to create premium gold pens, Baldwin creates a unique surface across your door hardware that is guaranteed to withstand the ravages of time. Living Finishes: Baldwin Living Finishes, which include Non-Lacquered Brass, Vintage Brass, Oil Rubbed Bronze, and Distressed Oil Rubbed Bronze, are designed to mimic the patina of a well-loved piece of vintage hardware, and as such will change and adapt over time naturally. For those who appreciate the well-worn look of aged door hardware, but still require the strength and durability of a Baldwin finish, Living Finishes are an ideal fit
