The Double Cylinder Door Knob is a secure locking solution engineered for both residential and light commercial entry systems where controlled access from both sides is required. Featuring a dual-key operation, this lockset enhances door security by requiring a key for entry and exit, making it suitable for exterior doors, side entrances, and areas where additional protection is necessary. The combination of a stainless steel knob and rosette ensures a solid structural presence, while the internal brass cylinder and brass keys provide reliable locking performance with smooth key rotation. Each set is supplied complete with latch, striking plate, fixing materials, and installation manual, ensuring a straightforward installation process for bulk orders and project applications.
