Single-point locks are essential hardware components designed for hinged doors, offering robust protection with a latch and deadbolt secured at a single central point. These locks are commonly found on residential entry doors, hinged patio doors, and security screen doors where a straightforward locking solution is preferred. Single-point systems are trusted for their reliability and ease of use, making them suitable for both new installations and as direct replacements for existing locks.

What Is a Hinged Single-Point Lock?

A single-point lock consists of a latch and deadbolt mechanism operated by a key or thumbturn, engaging the door securely into the frame at one location. Unlike multipoint systems, which lock at multiple points along the door, single-point locks focus force at the center, ensuring quick and secure locking for residential and light commercial applications. These are especially common on hinged doors where additional locking points are not required or retrofitting is being performed.

Compatible Applications and Brands

Replacement single-point locks in this collection are suitable for a wide range of hinged doors, including wood, fiberglass, aluminum, and steel models. These locks are compatible with popular door brands such as Marvin, Caradco, and Jeldwen, making it easy to match original equipment manufacturer (OEM) specifications. Many products are direct replacements for worn or outdated mortise locks and deadbolts, ensuring seamless retrofit and reliable operation. For example, see the 60mm mortise lock for Marvin, Caradco, and Jeldwen doors.
