To measure a cabinet lock, particularly a common type like a cam lock, you need to take several key dimensions to ensure a proper fit and function. These measurements help you select the correct replacement or a new lock for your cabinet or drawer.
Here are the essential measurements for a cabinet cam lock:
Key Measurements for a Cabinet Cam Lock
When measuring a cam lock, focus on the following parts:
- Cylinder Length: This is the length of the lock body (barrel) from the back of the head (where the key enters) to the end of the body. This measurement is crucial as it determines the maximum thickness of the panel or door the lock can be installed through.
- Cylinder Diameter: This is the diameter of the threaded or smooth body of the lock. It tells you the size of the hole required in the cabinet or drawer front for installation.
- Face Diameter: As mentioned in the reference, "The next measurement required will be the face diameter. As the name suggests." This is the diameter of the visible front part or head of the lock where the key is inserted. It helps in understanding the lock's appearance and footprint on the cabinet surface.
- Cam Length: Measure from the center of the hole on the cam (where it attaches to the lock body) to the farthest tip of the cam. This length determines how far the cam reaches to engage with the cabinet frame or strike plate.
- Cam Offset/Bend: Observe the angle or bend of the cam. Some cams are flat, while others have an offset (bend) upwards or downwards. This offset is critical for the cam to properly latch or secure the door/drawer.
How to Measure
You will typically need a ruler or calipers for accurate measurements.
- Cylinder Length: Measure the barrel length from the shoulder behind the head to the end of the barrel.
- Cylinder Diameter: Measure the diameter of the barrel.
- Face Diameter: Measure the diameter across the visible head of the lock.
- Cam Length: Measure the straight-line distance from the center of the mounting hole to the cam's end.
- Cam Offset: Note if the cam is flat or bent, and the approximate height of the bend.
Understanding these dimensions ensures you select a cabinet lock that fits the existing bore hole and panel thickness, and whose cam reaches correctly to secure the cabinet.
