This set of back door hardware contains everything you need to create a durable and secure exterior door, such as: B. a back door, a garden door or a barn door. The square set consists of a pair of door handles, solid rosettes and security rosettes with core pull protection. The Amsterdam door handle is made of stainless steel and finished with a matt black coating. Since the associated rosette is made of solid stainless steel, the risk of corrosion due to external influences is reduced. The concealed rosette has support cams that help keep it in place. In addition, the rosette has double springs, so that it is also suitable for a handle-operated multiple locking system. The safety rosette is equipped with a core pulling protection that protects the cylinder against pulling and drilling of the cylinder core. In addition, the security rosette is SKG***-tested, meaning it is a particularly heavy-duty burglary-resistant fitting. The rear door fittings are supplied including fastening material for installation.
