### **Schlage A199 Extension Link (18" Backset, 18-Foot Cable) Pros and Cons**

#### **Pros:**

1. **Extended Reach** The 18-foot cable provides significant flexibility for installations where standard deadbolts would require excessive keyhole placement or awkward leveraging. This is particularly useful in:

- **Sliding glass doors** (where a standard deadbolt may not reach the strike plate).

- **French doors** or **patio doors** with wide gaps between hinges and latch points.

- **Retrofits** where drilling a new hole for a standard deadbolt is impractical (e.g., existing trim or drywall).

2. **Compatibility with Schlage Deadbolts** The A199 is designed specifically for Schlage s **A-Series deadbolts** (e.g., A-Series 625, 626, 628), ensuring a secure and reliable connection. It maintains the same keyway and cylinder compatibility as the original deadbolt.

3. **Durability and Security** Schlage is a well-regarded brand for residential security products. The extension link is made of sturdy metal and is designed to withstand regular use without weakening over time. It includes a **keyed lock** (on the extension link itself) to prevent unauthorized removal or tampering.

4. **Easy Installation** Replacing a standard deadbolt with the A199 extension link is a straightforward process that typically requires only a screwdriver and drill (if adjusting the strike plate). No major structural changes are needed beyond the original deadbolt installation.

5. **Aesthetic Consistency** Since the extension link is concealed within the door frame (when installed correctly), it does not detract from the door s appearance. The deadbolt itself remains the focal point of the lockset.

6. **Versatility** Works with both **single-cylinder** and **double-cylinder** Schlage deadbolts, depending on the model. This makes it adaptable to different security needs (e.g., single-cylinder for convenience, double-cylinder for childproofing or high-security areas).

7. **Cost-Effective Upgrade** Compared to replacing an entire door or lockset, the A199 extension link is a low-cost solution to extend the functionality of an existing deadbolt without sacrificing security.

---

#### **Cons:**

1. **Limited to Schlage Deadbolts** The A199 is **not universal**; it is **exclusively compatible with Schlage A-Series deadbolts**. Attempting to use it with other brands (e.g., Kwikset, Weiser, or even non-Schlage A-Series models) will result in a poor fit or failure to function.

2. **Potential for Misalignment** If the original deadbolt was not installed perfectly, the extension link may not align correctly with the strike plate, leading to:

- Difficulty in locking/unlocking.

- Increased wear on the deadbolt mechanism over time.

- Possible jamming if the door frame warps or shifts.

3. **Keyed Lock on the Extension Link** While the keyed lock on the extension link prevents tampering, it adds an extra step to the locking process. Users must:

- First lock the extension link with the key.

- Then turn the deadbolt s key or thumbturn to secure the door.

This can be inconvenient in emergencies or when exiting quickly.

4. **Not Suitable for All Door Types**

- **Hollow-core doors** may not provide enough structural integrity to support the extension link s force when locking.

- **Very thick doors** (e.g., solid wood or metal) may require additional adjustments to ensure the deadbolt aligns properly with the strike plate.

- **Sliding doors with non-standard tracks** may still require additional security measures (e.g., a secondary lock).

5. **Visible Cable (If Not Installed Properly)** While the extension link itself is concealed, the **cable routing** must be done carefully to avoid visible gaps or loose ends. Poor installation can compromise aesthetics and security.

6. **No Warranty on Extension Links Alone** Schlage s warranty typically covers the deadbolt itself, not the extension link. If the link fails due to manufacturing defects, the user may be responsible for replacement costs.

7. **Potential for Weakness in High-Security Applications** While the A199 is secure against casual tampering, it is **not a high-security product** like a reinforced strike plate or a deadbolt with anti-drill or anti-pick features. For maximum security (e.g., in high-crime areas), additional measures (e.g., a secondary lock or reinforced door) may be needed.

### **Conclusion**

The **Schlage A199 Extension Link (18" Backset, 18-Foot Cable)** is a **practical and cost-effective solution** for extending the reach of a Schlage A-Series deadbolt in scenarios where standard deadbolts are impractical. It excels in **retrofits, sliding doors, and French doors** where space or structural limitations prevent the use of conventional locks. The brand s reputation for durability and security, along with easy installation, makes it a strong choice for homeowners seeking a simple upgrade.

However, its **limited compatibility** (only Schlage A-Series deadbolts), **extra locking step**, and **potential for misalignment** if not installed correctly are notable drawbacks. Additionally, it is **not a standalone high-security solution** and may require complementary measures for optimal protection.

### **Recommendation**

**Buy the Schlage A199 Extension Link if:**

- You have a **Schlage A-Series deadbolt** and need to extend its reach for a sliding or French door.

- You want a **low-cost, easy-to-install** solution without replacing the entire lockset.

- The door frame allows for **proper alignment** of the extension link with the strike plate.

- You are willing to **follow the keyed lock procedure** for security.

**Avoid the Schlage A199 Extension Link if:**

- You do not have a **Schlage A-Series deadbolt** (it will not work with other brands).

- Your door is **hollow-core or poorly constructed**, as it may not provide enough support.

- You require **high-security features** (e.g., anti-drill, anti-pick) that the extension link does not offer.

- The **installation would be difficult** due to door frame limitations or lack of proper tools.

**Alternatives to Consider:**

- If your deadbolt is **not Schlage**, look for **universal extension links** (though these are rare and may not offer the same security).

- For **maximum security**, consider a **reinforced strike plate** or a **secondary lock** (e.g., a sliding door latch).

- If the door is **structurally unsound**, a **new solid-core door** with a standard deadbolt may be a better long-term solution.

**Final Verdict:** The Schlage A199 is a **solid choice for its intended purpose**, but its usefulness depends heavily on the specific installation scenario and compatibility with existing hardware. Always ensure proper installation to avoid functionality issues.
