A single-cylinder lock requires a thumbturn on the interior side, meaning you do not need a key to open the door from the inside; simply turning the knob unlocks it. If you are interested in the knob styles offered by JW-LOCK, you can choose from various custom designs; standard options include round, oval, square, petal, cylindrical, and mushroom-head shapes. At the JW factory, the process goes beyond simple die-casting; the knobs undergo a series of chemical treatments and finishes, such as electroplating, wire drawing, and powder coating.
When selecting a lock cylinder supplier, do not focus solely on the knob’s appearance; the tactile feel and durability of the mechanism are equally important. The catalog features the factory’s best-selling knob designs, but if you require a unique or unconventional shape, the factory can create new molds or modify designs based on your drawings or specifications. Simply send an image of the door hardware to the factory, and the JW-LOCK team will assist you with further details.

It largely depends on the specific situation. The lock cylinder is primarily located on the interior side, making it a type of lock suited for privacy. If you install it on a main entrance door, relying solely on this cylinder poses a security risk; someone outside could easily open the door using tools or by accessing it through a glass window.
