Add an extra layer of protection to swing-in doors with the Prime-Line U 11126 Door Reinforcement Lock. Built from aluminum and finished in bronze, this compact lock combines durability with a discreet look that blends with many door styles. Designed to withstand substantial force, it helps deter attempts to kick in or tamper with a door while remaining unobtrusive in daily use.

The bronze anodized finish resists wear and corrosion, helping maintain a clean appearance over time. This reinforcement lock is quick to install on doors of varying thicknesses, making it a practical upgrade for extra security without the cost of a full alarm system.

Key Benefits

• Heavy-duty protection: designed to resist significant force and deter tampering when engaged.
• Durable materials: aluminum construction with a bronze finish for long-lasting appeal.
• Low-profile security: adds a first line of defense without changing the door’s look.

Installation and Compatibility

• Easy mounting: includes 3-inch hardened screws for a secure setup in minutes.
• Versatile fit: suitable for swing-in doors of various thicknesses; some doors may require mortising.

In addition to its primary function, this lock can be placed higher on the door to be child-safe, while still providing an additional layer of defense. For best results, view the manufacturer’s installation video and follow the recommended layout to ensure a proper fit. This product is intended to complement, not replace, a broader security strategy for your home.
