Buying Guide
What to consider when choosing a deadbolt for double doors:
- Security level: ANSI/BHMA ratings (Grade 1 is highest, Grade 3 is solid daily use). Higher grades offer more resistance to forced entry.
- Cylinder design: Double-cylinder locks require keys on both sides. This improves security but can hinder quick egress in emergencies.
- Backset and door thickness: Most options fit standard doors (1-3/8″ to 1-3/4″ thick); verify 2-3/8″ or 2-3/4″ backset for correct fit.
- Finish and durability: Finishes like satin nickel, matte black, or oil-rubbed bronze should coordinate with existing hardware while resisting corrosion.
- Installation complexity: Some sets include full hardware for double doors; others may require additional adjustments to fit hinges and strike plates.
- Key management: Consider whether you want keyed-alike cylinders across multiple doors to simplify access control.
