A paddle lockset is a type of door hardware that combines a latch mechanism with a paddle handle, often used in commercial and industrial settings. It is designed for ease of use, allowing doors to be opened with a simple push or pull motion on the paddle, which is particularly useful in environments where quick and efficient access is necessary, such as in hospitals, schools, or factories. The paddle lockset consists of several key components: the paddle handle, the latch mechanism, and the strike plate. The paddle handle is a flat, lever-like component that users press or pull to operate the lock. The latch mechanism is housed within the door and is connected to the paddle handle. When the paddle is pressed, it retracts the latch bolt, allowing the door to open. The strike plate is mounted on the door frame and provides a secure point for the latch bolt to engage when the door is closed. Paddle locksets can be either keyed or non-keyed. Keyed versions include a cylinder lock that allows the door to be locked and unlocked with a key, providing additional security. Non-keyed versions are typically used for interior doors where security is not a primary concern. The design of paddle locksets makes them ADA-compliant, as they require minimal force and dexterity to operate, making them accessible for individuals with disabilities. Additionally, they are often constructed from durable materials like stainless steel or heavy-duty plastic to withstand frequent use and harsh environments. Overall, paddle locksets offer a practical and efficient solution for controlling access in high-traffic areas, combining ease of use with reliable security features.
