For Surfaced Mounted Locks

Ensure your peace of mind - top lock cylinders for reliable security

The most important element without which a front door could not exist. Top lock cylinders are hardware that provide the community with a decent standard of protection and a sense of privacy. Top lock cylinders, also known as RIM cylind ers, make it possible to close the way for outsiders. Doors can have two cylinders, one on each side, allowing both sides to be locked with a key. They are used in situations where you want to prevent an unauthorized person from closing the door from the inside, such as in a store or warehouse. Cylinders also allow you to use a single cylinder mechanism - then the door will be locked and possible to open only from one side. Inserts in this category are compatible with most surface locks. If certification is important to you - we recommend reading the product description and the "certificates" tab. Inserts for top locks have a robust design and are created from durable materials that make it difficult to attempt break-ins and tampering. Some security devices for top locks offer a function for adjusting the taker, which allow you to adjust the tension and smooth the movement of the lock. In addition, there are cylinders available with a variety of security features, such as anti-burglary elements or additional protective shields. In addition to providing security, top lock cylinders can also improve the comfort of the lock. Thanks to their smooth, precise operation, opening or closing the door becomes easier and more convenient. The lock fittings come in brass, nickel, so they match different architectural styles.
