Keyed cam locks come in a variety of sizes to accommodate different applications and security needs. The primary dimensions to consider are the cylinder length, cam length, and diameter.
1. **Cylinder Length**: This is the length of the lock body that fits through the material it is securing. Common cylinder lengths include 5/8 inch (16mm), 7/8 inch (22mm), 1-1/8 inch (30mm), and 1-3/8 inch (35mm). The choice depends on the thickness of the material the lock is being installed into.
2. **Cam Length**: The cam is the flat, rotating part of the lock that secures the door or panel. Cam lengths typically range from 1 inch (25mm) to 2-1/8 inches (54mm). The length of the cam needed depends on the distance from the lock face to the point where the cam engages with the frame or strike plate.
3. **Diameter**: The diameter of the lock cylinder is another important dimension, with common sizes being 3/4 inch (19mm) and 7/8 inch (22mm). This measurement is crucial for ensuring the lock fits into the pre-drilled hole.
4. **Keying Options**: Keyed cam locks can be keyed alike (KA), where multiple locks use the same key, or keyed differently (KD), where each lock has a unique key. Master keying (MK) is also available for systems requiring hierarchical access control.
These locks are used in various applications, including cabinets, drawers, mailboxes, and enclosures, and selecting the correct size ensures proper function and security.
