Buying Guide: Key Purchase Considerations
- Door thickness compatibility: Ensure the plate fits your door thickness (common options include 1-3/8″ and 1-3/4″).
- Material and finish: Brass or antique brass finishes blend with traditional hardware and resist tarnish; solid brass offers durability over time.
- Door type: Confirm compatibility with metal, wood, fiberglass, or composite doors, and whether the plate supports external or internal applications.
- Installation simplicity: Look for pre-punched holes and included mounting hardware for a straightforward, tool-light install.
- Security level: A reinforced plate should cover the lock area adequately to deter forced entry and improve overall door integrity.
- Finish matching: If aesthetics matter, coordinate with existing doorknobs, hinges, and strike plates for a cohesive look.
- Repair vs. upgrade: Use reinforcement plates to repair vulnerabilities around the existing lock bore or to upgrade to a more secure latch area.
- Warranty and compatibility: Check product warranties and ensure the plate is rated for your door’s bore size and latch type.
