Profile cylinder is a locking mechanism distinguished by its symmetrical, elongated barrel shape that embeds directly into the door’s hardware, functioning as a core component in contemporary door locking systems. Its construction allows for the integration of various locking pins, which are manipulated by the insertion and rotation of the correct key, thus providing a secure method of access control. The cylinder is typically made from materials such as brass, steel, or nickel, enhancing its resistance to drilling and other forms of tampering.
The design of the profile cylinder facilitates its widespread use in residential and commercial settings due to its adaptability in various door thicknesses and security requirements. The double cylinder design, a variant, necessitates a key for operation from both outside and inside, offering heightened security but raising concerns about safety in emergency situations. Single cylinder versions, which do not require a key for inside operation, mitigate this risk. The profile cylinder’s compatibility with European and Scandinavian lock standards exemplifies its versatility in global architectural applications, accommodating differing lock mechanisms while maintaining a high level of security.
