Most door handles and pulls follow standardized designs. The standard door preparation consists of two main components: the larger bore hole (2 1/8 inches in diameter) where the handle passes through, and the smaller cross bore (1 inch in diameter) for the latch mechanism on the door edge.
The distance from the door edge to the center of the lock cylinder. Standard backsets are typically 2 3/8 inches or 2 3/4 inches. Some hardware features adjustable backsets to accommodate both measurements.
Commonly used for closet doors, this mechanism involves a spring-loaded ball installed in the door top that engages with a strike plate on the door frame to keep the door closed.
A supplemental locking device installed above the door handle. Available in single-cylinder (keyed exterior, thumb-turn interior) and double-cylinder (keyed both sides) configurations, with single-cylinder being the safer standard choice.
Comprising two metal plates connected by a removable pin, hinges secure the door to the frame while allowing movement. Security hinges may feature non-removable pins.
A cylindrical optical device with a fisheye lens that provides a wide viewing angle of the exterior while maintaining privacy and security.
The spring-loaded component that extends into the door frame's strike plate to keep the door closed. Exterior door latches typically include an attached faceplate for enhanced security.
Non-locking handles used where security isn't required, featuring only the latch mechanism.
Locking mechanisms without key cylinders, typically featuring an emergency release accessible from the exterior with a special tool.
Exterior door sets with key cylinders for security, available in various locking mechanism configurations.
Non-functional knobs or levers used for decorative purposes or with alternative latching systems like ball catches.
Recessed locking mechanisms commonly used on French doors, engaging vertically into the frame at top and/or bottom.
Traditional locking systems requiring specialized door preparation, now available in high-quality reproductions for restoration projects.
Proper alignment between the latch and strike plate is critical for smooth operation. The strike plate's curved "lip" guides the latch into position, while its center hole receives the extended latch to secure the door.
