No Unsightly Screws Screws on the face of the door knobs are not only unsightly on their own, they would also ruin the overall design of your house. Our elegant design eliminates screws on the surface of the door knobs to ensure a seamless integration of function and aesthetic. Ultra-Durable latches Instead of adjustable latches, we include high quality zinc alloy latches with our door knobs. These latches are made specifically for your doors. We stock both 2 3/8" and 2 3/4" long latches. 2 3/8" latches will be included unless you request 2 3/4" latches explicitly after placing your order. Our zinc alloy latches are at least 10 times more durable then the adjustable counterparts. We would not compromise durability and quality for the convenience of not having to cater to the need of each individual customer. Heavy Duty Construction Constructed from die-cast zinc alloy components, our knobs are not only aesthetically appealing, they also offer enhanced security and durability. All components are made from solid zinc alloy instead of hollow stainless steel. They could not be easily damaged or dented, and they will look new many years down the road.
