Review PROSOURCE Double Cylinder Deadbolt Brass Gold Adjustable Latch Keys Model

Introducing the Prosource 20337 Double Cylinder Deadbolt Latch Key Set, a reliable and secure solution for your home or office entryway needs. This deadbolt latch key set comes with two keys that can be used to lock and unlock the deadbolt from both the inside and outside of the door, providing an added layer of security and convenience.

The Prosource 20337 Deadbolt Latch Key Set is a double cylinder design, meaning that a key is required to both turn the lock from the inside and outside. This feature helps to prevent unauthorized entry, ensuring that your home or business remains secure. The keys are precision-engineered to fit snugly into the lock cylinder, providing a smooth and easy operation every time.

The deadbolt latch is made from solid brass material, which is both durable and resistant to corrosion. This ensures that the lock will last for years to come, even in harsh weather conditions. The brass finish also adds an elegant and classic touch to any door.

The Prosource 20337 Deadbolt Latch Key Set is easy to install, requiring no professional assistance. It comes with all necessary hardware, including mounting screws and a latch assembly. The installation process is straightforward and can be completed in just a few simple steps.

In summary, the Prosource 20337 Double Cylinder Deadbolt Latch Key Set is a high-quality and reliable security solution for your home or office. Its double cylinder design ensures added security, while the solid brass construction provides durability and resistance to corrosion. The easy installation process and inclusion of all necessary hardware make this a convenient and hassle-free purchase. With two keys included, you can rest assured that you always have a backup on hand, providing peace of mind and an added level of security.

1. Enhanced Security: A double cylinder deadbolt provides an extra layer of security as it requires a key to both sides of the door for unlocking.

2. Durable Construction: This deadbolt is made of solid brass and comes with a reinforced steel strike plate, ensuring long-lasting use.

3. Weather-Resistant: The brass construction also makes it suitable for outdoor use as it is resistant to rust and other weather conditions.

4. Adjustable Latch: The adjustable latch allows for customization to fit various door thicknesses.

5. Keyed Alike: If you have multiple doors in your home, you can key them alike for convenience.

1. Fire Hazard: Since a double cylinder deadbolt requires a key to open from the inside, it may pose a fire hazard if used on the primary entry door to a residence. In such cases, a single cylinder deadbolt or a deadbolt with a thumb turn is recommended.

2. Difficulty in Emergency Situations: In emergency situations, a double cylinder deadbolt can make it difficult to quickly exit the premises.

3. Complex Installation: Installing a double cylinder deadbolt can be more complex compared to a single cylinder deadbolt, as it requires drilling additional holes for the keyed entrance.

The Prosource 20337 Double Cylinder Deadbolt is an excellent choice for securing exterior doors in places where convenience of entry is not a primary concern. Its durable construction and enhanced security make it a worthy investment. However, it is essential to consider the potential fire hazard and difficulty in emergency situations before deciding to install it as the primary entry door deadbolt.

For residential applications, I would recommend considering a single cylinder deadbolt with a thumb turn for the primary entry door. This will provide the necessary security while maintaining the convenience of quick access in emergency situations. For additional security, install a double cylinder deadbolt on secondary doors or those that don't require quick access.
