When it comes to door locksets, there are several basic components that work together to provide security and functionality. Whether it's for windows or doors, understanding these components can help you choose the right lockset for your needs.
1. Exterior Escutcheon:
This is the decorative plate that is visible on the outside of the door. It typically contains a keyhole for inserting and turning the key.
2. Interior Escutcheon:
The interior escutcheon is the plate that is visible on the inside of the door. It is usually connected to the exterior escutcheon and may include a thumb turn or lever to lock or unlock the door from the inside.
3. Cylinder:
The cylinder is the mechanism that the key is inserted into. It contains pins and tumblers that align to allow the lock to open when the correct key is used.
4. Latchbolt:
The latchbolt is the part of the lockset that extends from the edge of the door into the doorframe. When the door is closed, the latchbolt goes into the strike plate, securely holding the door in place.
5. Strike Plate:
The strike plate is a metal plate that is affixed to the doorframe opposite the latchbolt. When the door is closed, the latchbolt fits into the strike plate, creating a secure lock.
6. Deadbolt:
A deadbolt is an additional locking mechanism that provides extra security. It is typically operated with a separate key or thumb turn and extends deeper into the doorframe compared to a latchbolt.
7. Rosette:
The rosette is a decorative plate that surrounds the cylinder on the exterior escutcheon. It gives the lockset a finished look and adds aesthetic value.
8. Backset:
The backset is the measurement from the edge of the door to the center of the lockset. It determines how far the lockset is installed from the door's edge and is usually 2-3/8 inches or 2-3/4 inches.
9. Faceplate:
The faceplate is a metal plate that is installed on the edge of the door. It provides reinforcement for the latch, deadbolt, and other components, ensuring they are securely attached.
10. Spindle:
The spindle is a metal rod that connects the interior escutcheon to the exterior escutcheon. It allows for the transfer of motion from the thumb turn or lever to the latchbolt or deadbolt.
11. Thumb Turn:
A thumb turn is a small lever or knob that is located on the interior escutcheon. It can be turned by hand to lock or unlock the door from the inside without the need for a key.
12. Strike Box:
The strike box is a metal component that is installed in the doorframe. It provides additional reinforcement for the latchbolt or deadbolt, making it more difficult to force the door open.
Understanding these basic components of a door lockset is crucial in order to make an informed decision when purchasing one. Whether you are replacing an existing lockset or installing a new one, consider the security needs of your windows and doors to select the right lockset that will provide the necessary protection.
