### **Cons of Using the Schlage P509-640 Deadbolt with L583-467 Spacer**
1. **Limited Effectiveness Without Proper Installation**
- If the **spacer is not installed correctly**, it may not provide the intended reinforcement, leaving gaps that could be exploited.

- Some users may need to **shim or adjust the hinge side** to ensure the door swings smoothly after installation.

- While the **deadbolt and spacer improve security**, they should be part of a **larger home security strategy**, including:- A **reinforced strike plate** (at least 1" thick with heavy-duty screws).
- **Window locks and security film**.
- **Smart home security systems** (if budget allows).
- Relying solely on these products may leave vulnerabilities if other weak points exist.
4. **Aesthetic Limitations**
- The **spacer is functional but not decorative**, meaning it may not enhance the door s appearance.

- The **P509-640** comes in **limited finish options** (primarily brushed steel), which may not match all decor styles.
- The spacer is **one-size-fits-most** but does not accommodate **very narrow or wide frames** without modification.
