Installation at a Glance

The U 11449 ships with 3" hardened screws to anchor the mechanism firmly. Pre-drill holes with a 1/8" bit as directed to avoid stripping screw heads. Depending on your door, some mortising may be needed to achieve a clean fit and full clearance.

• Includes 3" hardened screws for strong anchoring.
• Pre-drilling is advised; avoid max torque settings to prevent damage.
• Mortising may be required for a flush, clean installation on certain doors.

Notes and Pairing Ideas

For enhanced convenience, you may consider pairing this reinforcement with compatible accessories. While it’s designed to complement existing hardware, it’s best used as part of a layered approach to door security. Keep in mind the product is a secondary barrier and is not a sole replacement for a complete security system.
